Maybe later... nothing really compels me at launch. Luigi's Mansion gets old fast (after an hour according to IGN Japan), Wave Race doesn't excite me too much, and nothing else is a must-have yet.
The RE series looks good, but again its pre-rendered backgrounds, and unless they balance the gameplay and fix the dasm controls then no thanks.
Rouge Leader does look great - but I'll wait to see.
I'm dissapointed in the new look of Zelda, but will try to keep an open mind.
Anyway, the GC holds the most chance with me of being my #2 home system. I'm thrilled with my PS2 and GBA right now, and very non-excited about the M$-Box...
