obviously there is gonna be something new.
Heres my take on this topic
http://saiph-charon.deviantart.com/journal/What-s-their-next-move-2-0-335223314
1.-Genesects reveal was rushed
2.-The DS is dead
3.-Gen3 games are as outdated as Gen1
Now on to why each of these matters and what the consequences are.
1.The reveal of Genesect (and wifi-download release shortly after) at the end of Keldeos Movie (Meloetta was in the short that plays before it) was completely unexpected by everyone.
So they have nothing left to drag this generation out a bit longer like was the case with Arceus, which was neatly being promoted along the GS remakes in generation IV. Generation V can therefore be considered finished.
Since only the supporting legendary roles of the next movie are revealed in the summer (and the actual star several months later in February), it is clear that some new Pokemon will be revealed this Winter. And that will signal a 6th generation being fully in development.
2.With the DS out of the way for good, it simply means that any future game will be made for the 3DS, which has been out for almost 2 years now. Its way overdue for a big franchise like Pokemon to start helping Nintendo sell its current handheld anyway.
This means that the next game will technically run on a new engine, new graphics etc, which basically makes it the game that sets the style that will last through generation 6.
3.The majority of people are expecting RSE remakes. Sounds easier than it is for Gamefreak to realize for a lot of minor reasons (like the issues that arise in the plot if they decided to skip Emerald like before, or the fact that RSE took place a decade ago next to recent games), and major reasons (it does not fit well with the fact that they need to do something new). But the thing is also, that RSE are just as old as the first remakes of the first games. Which begs the question, how justified is it to continue remaking newer games when the oldest become the oldest again?
And this emerging irony is why I think it is time to abandon the "remake concept" and replace it with something fresh. Especially now when the "simple third version concept" was just replaced with something actually creative, "sequels".
The conclusions from this:
1.-Gen V is finished
2.-next game will be Gen 6 "style" (a proper 3DS game)
3.-if Hoenn will be featured, it will not be simple remakes
To me, the less likely possibility is that Gamefreak goes ahead and milks the Hoenn-nostalgia cow, with either a RSE-sequel or a RSE deeper retelling.
The much more likely possibility seems to be Generation VI, because it makes much more sense to start the new technical generation with, and because we will know at least one new pokemon half a year before it can possibly be released, which won't be featured in a RSE-whatever game...
I'm sure it won't be another "fresh start" like RSE or BW, it will not drop another ~150-bomb. So new places, new pokemon, new plot, new legends are all a given.
It will either be an expansion (like Johto was to Kanto):
-for Unova
introducing new starters, new evolutionary stages for mostly if not exclusively Unova-Pokemon, along with a handful of casual Pokemon lines,
maybe more Plasma or a new group lead by any of the sages,
its own legendaries, perhaps a better glimpse at the original dragon for the post-game
-for Hoenn
which would be a much more elegant way of bringing Hoenn back to live than some simple cash-milking copy&paste remakes. Hoenn could be a post-game visit much like Kanto in GS, or most of it could be part of the main plot (similar to how BW2 explored a bigger Unova).
The starters could be new or the good old RSE ones (which IMO would be quite smart, since the Fire type for example could have more new casual Fire Pokemon instead of consisting mostly of starters LOL), there would obviously have to be new main legendaries, but related to the Hoenn ones. One wild idea would be 2 behemoths employing the other 2 weather effects (which both happen to be hazardous), Hail and Sandstorm, much like Groudon and Kyogre.
It would be taking place more than a decade after the events of RSE obviously, so there could tons of old faces, any younger relatives and kids for us to meet along the way and plenty other nostalgia elements.
-in general (like Sinnoh did)
simply a huge new region, but a unique mix of old pokemon with some new, plenty new stages, a big plot etc.
All 3 seem very plausible and interesting. But the 2nd would get rid of the need for RSE remakes and remakes in general.
The next thing to look forward to, is clues about the next movies star when the title will be revealed in December.
Then the star itself, a new pokemon, should be revealed around February.
And announcements of the next games at any point after that depending on how much longer it will take them to finish.
