I'll probably buy Resident Evil 5, Street Fighter 4, Halo 3: ODST, Tekken 6, and Mario & Luigi 3 in that order.
I was really looking forward to Fire Emblem: Shadow Dragon, but the changes they made are too radical for me. I'm a huge Fire Emblemer, but the ability to change character classes, get your friends' characters, and buy things online is too much for me. They make it too generic; half the challenge and fun of the first one on GBA was trying to raise your fledgling younger units (Nino, Rebecca) into terrors on the battlefield while keeping them alive. You got attached to them.
And the harder difficulties are impossible without using that stuff. Gayness...
