OMG, excite. I'm genuinely really looking forward to this, I think partly because we haven't had a 3D Mario in like 4 years and partly because even though the 3D sub-series was good, the games seemed to have slightly more modest ambitions than the Galaxy games. Whereas this seems like a proper attempt to outdo all the previous games.

Chances of picking one up are quite high I think, but chances of a good deal are slim. You'll probably pay full RRP in store. Even online £10 with a code seems to be one of the better console deals so far.
