Zero?

Well, maybe it will outsell it for the first seven day period...

once the holidays roll around the Wii will likely be flying off the shelves as fast as they can be stocked again. Its not just appealing to kids, but to many baby boomers and grandparents. Just wait for the Wii version of the Beatles Rock Band that game is going to do amazing sales on that platform.

lol, like ps3 would actually surpass wii in weekly hardware sales with 300$ price XD

Two or three weeks.

I second what many have already said. Two or three weeks. It could be actually five or six in Japan.

From what I remember, the price of the Wii and the 360 is going to rise in the UK.

The PS3 will outsell the Wii for one week worldwide, then the Wii will outsell it by a fairly slim margin the next week.

I say that Wii will still outsell ps3 even on the first week....

One week. Could be zero, could be two by a slim margin.

zero - 1 week
