Not that I'm talking down events, but yes they have prioritized a specific class of player... at least the pre-DS ones did. They prioritized the player that could travel great distances for a pokémon they could not get any other way. I know when I was little my mom wouldn't drive the 6 hours to Atlanta just for me to get a pokémon.
As for having to wait longer to get a special Reshiram, it would be SPECIAL after all. Remember Regigigas from TRU? We got that well after everyone had already gotten Regigigas from Pearl or Diamond. The difference was that this Gigas was special, therefore still relevant. If the Reshiram has a move it can't get any other way, then it will still be relevant. Even if the third version IS out and you can get Reshiram in it (which is a hypothesis based on older games, they could make it where you can't get Reshiram and Zekrom in the game for all we know) the event Reshiram would still be worth having, if only for the special move it would know.
As for waiting for the third movie for a Kyurem introduction... that's a hypothesis. I'm not GF. I don't know, I'm just basing my hypothesis on the fact that there are 3 other event exclusives (Kerudio, Meloretta, and Genosect) which means thier could be up to 3 more movies not counting the Zekrom one. It's highly possible that each movie will feature 1 event exclusive (like Victini) and one dragon (Zekrom) leaving one event to get it's own movie or for a final movie involving ALL THREE dragons like the Arceus movie.
The final topic, the topic of Kyurem sharing moves with Zekrom and Reshiram, it doesn't matter how powerful Kyurem's level up signature move is. That doesn't mean that Freeze Bolt or Cold Flare won't end up on Zekrom and Reshiram. Let's say for sake of argument that they don't. That means that if the movie gives away Zekrom, there is NOTHING special about it. It won't unlock anything (unless potentially in a third game... but it's way to early for them to be makin events like that.. Regigigas only came out a couple months before Plaitnum). As events go that's pretty lame. I don't understand why all three can't get thier signature moves, plus event moves.. because as far as events go.. anything goes. The fact that event moves were even made shows that it's a possibility. I still site Arcues on this one. Palkia, Dialga, Giratina, and Arceus each have one signature move.. yet the event Arceus has 4.. one from each Dragon and then Judgement.
Anyway, I'm not saying they will do that. For all I know Kyurem will get the event moves and Zekrom and Reshiram won't. I was simply hypothsizing.. and since Freeze Bolt (Freeze, Ice - Bolt, Electric) and Cold Flare (Cold, Ice - Flare, Fire) reference two different types, I'm simply stating it as a possibility.
One final note, however, how do you know when the third game will be released? If your basing it on what the company has done before, that might not work. TPC is trying a lot of new stuff this gen so I don't see what's wrong with a little hypothesizing. I made my hypothesis, I'm ok with it, if you not.. then oh well. I'm sorry if Kyurem gets the raw end of the signature move deal, but that happens. Ask Mewtwo.. it didn't get a signature move til gen 5... and it's been around since gen 1. Or hey, for that matter Kyogre, Groudon, and Rayquaza. They still don't have signature moves.
