The special announcement by Pokemon is the confirmation of Pokken Fighters or better known as Pokken Tournament. While originally it was announced as a Japan Arcade game to be released in 2015, it was later implied that it will probably be released as non-Arcade game (aka Console).
Recently the Official International YouTube Channel has uploaded an English trailer, giving me hope that there will be International releases.
When this game is released for Consoles it will probably be only for the WiiU, and here are my reasons:
1. In the Trailer the graphics on the characters, especially Lucario is way too high for a handheld like the 3DS.
2. Usually games like this are not made for the handheld, plus they don't have any Pokemon games for the WiiU at the moment and this would be the perfectly good opportunity to make good money on both the Wii U and the game itself.
3. While the WiiU is getting a lot of amazing games there isn't any games that directly appeal to the Pokemon Community, other than Smash 4, because of the characters.
