I've never been a Banjo Kazooie fan, 'cause I'm not big on platformers, but N&B has won me over. After Gears 2 and Left4Dead, this is gonna be a must buy for me, at least if its as good as the demo.
Not day 1 though, since I'm not gonna have money for a loooooong time :P
GOTY Contestants this year: Dead Space 2, Dark Souls, Tales of Graces f. Everything else can suck it.
