I don't forsee the system being readily available for a good, long time. It may not be sold out everywhere at once, but it'll remain sold out at least somewhere for the rest of 2008 and some time to come. Personally, I'm expecting Nintendo to pack WiiFit in with the machine in NA and Europe to insure that the system doesn't stop being the hot thing to buy in those two regions. Come 2009, Nintendo will be ready with a GBColor-like upgraded WiiHD which will remain sold out through 2011, at which time Nintendo will not be able to launch a second "Wii Fit" that keep the system sold out for another year.
So, yeah, Spring/Summer 2011 is when Nintendo will stop being sold out.
And to put a finer point on it, I think Nintendo will increase production two more times this year: Once to 2.2 million units a month starting in April and again to 2.5 mil/mo in October.
You do not have the right to never be offended.
