Alright I'm a long time reader of these posts, but I found this topic so fascinating I had to create a username and add my two cents:
I believe what is causing the biggest disagreement is the fact that the OP is looking at it from a Macro point of view (looking at the market as a whole), whereas most of the replies are looking at it from a Micro point of view (just their opinions).
That being said I can agree with his logic the Wii is providing the most value (as someone stated earlier, that is perceived value, since sales are an indicator of perceived value, you won't know the true value until you get home and play) to the market as a whole. If it wasn't, it wouldn't be the biggest seller.
Personally I own all 3 systems and will say from my Micro point of view the Wii has the least value. I tend to put in more time with my 360 and PS3 games and the Wii has almost became a dust collector at this point.
