It's kinda funny how everybody talks about wii being the worst in selling software, but it sells the most software and has about the same attach ratio then other consoles and the bigger your userbase the smaller your attach ratio. Just look at ps2.
Pointless discussion is pointless discussion. I don't see the ps3 selling much software either tbh, how many 5million sellers does that console already have? 1? How many 1million sellers? A lot less then the wii, I'll tell you that.
Conclusion: All consoles are domed, who gives a fuck anymore.
