Hm, guess I'll have to pre-order a Wii U now!
I'm joking. The game hasn't even a release date yet and people are typing that sort of nonsense. If Bayo 2 was the ONLY thing convincing you to pre-order, then why not wait til the game releases to buy the console? Who knows, it might be cheaper, or sold used, by that point and you can save yourself from buying a console you only want for the purpose of one game.
This also assumes that the game will be great. I'll admit, the fan in me says "of course it'll be great!" but what if it's... not great? What if it doesn't stack up to the first and is merely decent? Going to be very interesting to see the first reviews.
Stop being so negative, why won't you give a Sega game a chance?
I do agree with you though, I haven't heard anything about release date yet, so I'm not about to pre-order the console just yet. I don't think it's likely to sell out anway.
If there is some really good pre-order bundle or offer I might bite, but otherwise I'll wait and see what the lineup looks like.
I also share your concerns. I think it's most likely to be awesome, but look at how shit DMC2 was after the brilliant DMC 1 for example. Also, I didn't think of this until later, but the Wii U controller looks shit, so hopefully they have a good controller come out for it too.
