As much as I hope that the new CoD IS on the Wii (mainly due to me being a Wii fanboy), I will still get it for the PS3 or 360 due to the online connection of those systems compared to the Wii. I love the aiming, but online sucks respectively.
That said, I'm still looking forward to Con2 as it is an exclusive title. That is what makes is so appealing.
