There will be 157 new Pokemon, bringing the total amount to 650.
A 157 Pokemon, thats a great number, they already showed us 12, so Game Freak has 145 chances to either impress me or to disappoint me.
In one way i'm happy we are know at 650, seeing this number only me excited for Gen VI, maybe by Gen X we'll have at least 1,500 species of Pokemon.
Like how Giratina compliments Dialga and Palkia, a large, green cobra will accompany Reshiram and Zekrom.
I like cobras, they're my favorite snake...but i'm curious as to how a Green Cobra is relevant to Yin-Yang, Black&White, Fire/Electric or The Sky...as for typing this might be our first Poison legendary...i hope its Water/Poison, indicating that it might be based of a Naga...
Tauros will have an evolution: Minotauros. It stands on two legs.
I have actually been predicting this for a long time along with a possible pre-evolution. In fact on deviantart there are many Minotaur evolutions of tauros and a few actually share the same name Minotauros, in fact one of my fakemon i made is also exactly named Minotauros...hmm maybe Game Freak does frequent deviantart...
In previous games, either through moves or through abilities, players were able to alter the weather conditions of the battle field to boost certain types. For example, Groudon's Drought summons sunlight, which boosts Fire-type moves by 50%. In Black and White, players will be able to collect certain items that alter the weather conditions of the battle field. Approximately twenty of these items will affect the weather conditions so that they will boost certain types (kind of like Stadium cards in the TCG?), with some types getting added bonuses depending on the item. As a side note, in today's CoroCoro scans, there was a screenshot showing a new weather indicator (we overlooked it), which could give credence to this claim.
This is really interesting, initially i was never a fan of weather as a possible battle strategy mostly because it would waste a turn using a move that did no damage...
but this will even the playing filed, meaning it will be easier to get STAB bonuses and weather-damage bonuses...Pokemon battles just keep getting better and better...
One example will be setting up a Poison Field, which causes all Poison-type attacks to gain 30% accuracy, Sludge Bomb to have a 100% poison rate, and the effects of Toxic Spikes' poison to have an immediate effect
Oh sick, if this sort of "field" exclusive bonuses are available for every type, than O_O, Pokemon battles will never be the same, the amount of skill needed to win a battle in which you and your opponent share the ability to improve the damage/usefulness of attacks to such a high degrees really will be a challenge. I'm really excited for this aspect.
Black and white, good versus evil, and yin and yang are going to play a major part in the plot. However, unlike previous Pokemon games, the decisions and choices you make will "influence" the plot of the game. If you make "good" choices, you might get certain help or items, whereas "bad" choices could have negative effects. The point is that the plot will not be as cut-and-dry as previous games, changing depending on the player's actions.
Now this, this is the real deal, Pokemon with a real mainstream-rpg style story...
Where the players actions influence the progression of the story, i love these kinds of games, as for making bad decisions, i really maybe in the future make a Pokemon game in which one can choose to be the bad guy, and join the "Team Rocket" of the game, and maybe have a separate campaign.
Also what would be interesting for the future is a giant Pokemon MMORPG, in which there are factions: Trainer, Coordinator, Professor, "Bad-Guy" and each has a different for of playing.
