Are you really suprised? I mean technically Nintendo has always pulled this trick. The SNES wasn't a proper 16 bit system depending on who you believe. The NES N64 and the Cube was the only systems nintendo actually built using the new technology at the time. The others were throwbacks put under a new hood.
Here's what I find strange. If the SNES wasn't a truly 16-bit system, then what was the Genesis? The Genesis wasn't exactly proving it was better than the SNES and was being sold as one too.
Anyway, I'm not too fussed about Nintendo's performance so far. This happens like every time now, and then it turns around and people go "Oh wait, I am a hypocrite" and then suddenly say Nintendo has lightning in a bottle. The news coming out of the latest Nintendo Direct actually shows they have a solid plan going into next year.
Edit: Also, I find it amazing that people actually think Bayo 2 will be ported to another console. It's a Nintendo game, SEGA only owns the license while Nintendo paid for EVERYTHING. SEGA or Platinum have no say, and even less so with the Wonderful 101.
