You were just referring to GAF? Well, then no. That conversation will likely end with this thread. I thought you were referring to the gaming market as a whole, which has proven time and time again that they care a lot less about graphics than enthusiasts.
It's not just GAF. I mean, that's why sites life DF exist.
People who bought a Wii for wii sports etc won't give a shit to begin with.
But we did get to a point where people looked at that japanese garden demo and were already talking about how the WiiU is going to blow the PS3/360 away. Then you get that X.gif thing constantly.
So yes, in that context, the discussion "Is WiiU good enough to best the HD twins' graphical showcases?" is very lively, and both sides keep it going, but by the time that question is concretely asnwered, people will most likely have moved to a whole new standard.
