sony will be on top for this generation of the console wars. they will however lose market share.
I think last gen it was like 70% MS for Sony, this time I bet they are around 50% with MS picking up a bit and the Wii helping nintendo regain some lost ground.
As far as the Wii…all the reviews ive read from people that have gotten to try it say they for the most part enjoyed it. Plus i watched a video of this dude playing zelda for a few minutes and it looked like it was pretty sweet…but time will tell for sure.
