As we've suspected for weeks now, Genesect is going to be officially revealed this month, and technically it already has due to the Movie 16 teaser shown after the special airing of Movie 15. Clearly, Genesect is receiving the Victini treatment, which was also revealed via a movie teaser two years ago. But as we know, the reason for Victini's early introduction was the decision to distribute it via Wi-Fi upon Black and White's release. It is safe to assume that something similar is going to happen with Genesect, as otherwise the early announcement would be pointless.
The problem is that unlike Victini, Genesect doesn't have an in-game event where it is catchable. The Keldeo and Meloetta movie events are already being used to promote B2W2 (although neither Pokémon unlocks anything significant exclusively in B2W2, since even Resolution Form is merely an aesthetic change), so there is arguably little reason to use Genesect to promote those games. Even if there were such a reason, one would think that Game Freak would at least bother to program a new event for Genesect, which they didn't do. The only in-game event Genesect has (which remains unchanged from Black and White) will most likely not be unlocked until the movie promotion, since the Cassette items are the only thing that can properly distinguish the movie Genesect from the one distributed via Wi-Fi (much like V-create in Victini's case). For this reason, I'd be surprised if Genesect were distributed with a fateful encounter flag.
So how is the distribution going to work? Will Genesect simply be downloaded via Wi-Fi without any in-game event? That is certainly possible, but it would be an odd move promotion-wise; the Victini distribution wasn't an act of generosity, but rather it served as an incentive to buy Black and White soon after their release. Again, with B2W2 that function is more or less being fulfilled by Keldeo (the start of its distribution coincided with B2W2's release) and to a lesser extent Meloetta. I suspect that Genesect is going to be used to promote an upcoming game, but obviously not a main series one. Precedent for this exists in the form of the Manaphy egg in the first Ranger game, but in this case I believe that the next release is going to be a Wii title compatible with the Generation V games.
So how about it? Is there a good reason for the lack of a new Genesect event in B2W2?
