Not really. Iwata said "platform". That could be almost anything. It could be an entirely new device, it could be a new gaming API, new hand held, new home console, new fusion console, new online platform, new tablet device... There are so many possibilities. If it does end up being a new console, it doesn't makes that much difference anyway because he said it won't be announced till 2016 which means it likely won't release till mid to late 2017.
Basically, if you want to buy a Wii U, you might as well. There is already a great game catalogue and there looks to be more on the way.
Nobody can make the decision for you, so take a peek at what is out there and see if it interests you. If not, then prob not.
If you do, I would highly recommend a crap ton of games lol.
SM3DW
Smash Wii U
Bayo 2
Wonderful 101
Pikmin 3
MK 8
Donkey Kong Tropical Freeze
Lego City (long load times... but awesome game)
ZombiU is so cheap now you can't pass it up
