First, I must say : I love my wii and I don't hate the other systems, in fact I may buy a 360 this year, and a PS2 and PS3 sooner or later.
What you describe is exactly "THE END OF GAMING AS WE KNOW IT" scenario that all the wii haters fear.
If that ever come true, which I don't think so, I my initial reaction would be... ¿where did all the hardcore games go?
I am sure the real scenario will be different, but if what you describe ever comes true I will become a RETRO hardcore player.
I will treasure my Wii to keep playing its good old hardcore games. If I have never bought the 360 and PS3 I will strongly consider buying either the xbox 720 or the ps4 for my wife and my kid, and expect this systems have Retro Compatibility so I can play the good old hardcore games using the traditional controllers.
I think the actual Wii haters will start hating his former favorite gaming brand (as some nintendo fans did) and maybe leaving gaming forever hating the Wii even more and everything they considered casual.
But I don't that would ever happen...
Frybread: answer to me honestly, please, do you really think this is the future of gaming?
