I disagree with all of them.
I expect Galaxy 2 and Other M in the summer. There are defiantly not strong enough to carry the Christmas season. Also, talking to a Gamestop employee, he said June for Galaxy 2. They are also taking reservations, but they will do them as soon as they can, so it may not be a big deal. Zelda Wii will be in the Christmas and will be the headlining Motion Plus game to square off with Arc (the wand) and Natal. It will be joined by another game for sure.
