I take IceCold and Cap's stance: this is exciting news, but I'm afraid it will backfire. Mediocre game quality for us, poor sales for Ubisoft due to spreading out sales. What I do like is that this lineup it covers more genre bases. Blazing Angels may get sales purely because it's the only dog fight game on the system.
Even so, I'm at least one person who probably won't buy any of these. Maybe if they get glowing reviews, but right now I've already got Zelda, Metroid, WarioWare, Red Steel, Rayman, Excite Truck, Sonic, and Super Monkey Ball on my tentative "must buy" list. Suddenly I've gone from my E3 "must have EVERY GAME!" mentality to, "There's just too many, I have to narrow it down".
