I made my last prediction a while ago, so with all that has happened in this year so far, I expect the following will happen:
In December 2012 the title for the next Pokémon will be revealed, with Genesect listed as having a starring role. However, in February 2013, CoroCoro Magazine will unveil a Generation VI Pokémon, which will be revealed as being the main star. Then, in April/May the Generation VI Primary Pair will be announced, which will begin the chain of CoroCoro and other sources featuring new Pokémon and information about the games in preparation for a June Japanese release, with the Pokemon unveiled in February (or its pre-evolution) being distributed to copies of the new game when the movie opens in July, with a special Genesect being a pre-order bonus. Said Gen VI pair will be released internationally in October.
During the first half of that year, we will also see a Pokémon spin-off game released in Japan, then possibly a Wii U game towards the end of the year.
Gen VI's pair will be released in September in Japan, with an international release in 2014. The main movie distribution will be a special Genesect (be it shiny, have a special move or otherwise), with the pre-order tickets being the option to download a Pokémon onto the Gen VI games from Pokémon Centre stores when they are released.
