Xenoblade - probably flop. I don't think you're getting much change for a full console release with @ best $5M revenue. At best probably broke even, definately not a success.
MH3 - Probably break even, possibly a loss. Advertising costs money, I think this one didn't really make any to be honest.
RS2 - Flop. Probably are not coming back for round 3.
Metroid- Probably not worth Nintendos time. Little more than break even.
Boom Blox - Success! Though not really going to move the bottom line.
Tease.
