The biggest limiter for the Wii outside the supply constraint is the actual size of its true potential market. It's quaint to say that anybody can pick up and play, and it's pretty true overall, but not everybody who can be a part of that market is going to be.
Oh, and on the legendary 120mil of the PS2: how many of those are replacement units, I wonder? Probably most of the early models. I know I've owned 2 PS2s over the years, since my original was traded in for a slimline after said original stopped reading non-game DVDs and game CDs. I'm sure I'm not even close to the only one who's done this, either. Nintendo consoles tend to have a lower failure rate, and much better policies on hardware repair, meaning there won't be as inflated of sales from replacement models.
Sky Render - Sanity is for the weak.
