hmm... I'm not sure about consoles being shovel, I mean, I have my wii since launch and it still works perfectly, same with my gamecube, haven't bought the wii u because it arrives the 12 of december here in Chile. But man, I just use my consoles to play games, that's why I buy them, because going the pc way is just too expensive and because nintendo always focuses on making games that can be played and enjoyed by everyone.
I'm more concerned about developers with their f*****g next gen engines and next gen gaming... where single player is almost no existent or it's so much complicated that I can barely play it... I mean, now racing games have open worlds and s**t... I have to stop on a corner to play a race and most of games have so much stuff going on that everything has glitches and bugs... That's the only thing that concerns me... but actually I have no problems with that when nintendo is doing the games... but I know that nintendo is not going to make a shooter or an action adventure game or an arcade racing with a more realistic theme (not a simulator)... That's up to 3rd party developers...
Though I have no problems with huge games with tons of stuff going on... but I think it's just too much, every game has to be big in order to sell... back in the 90's it wasn't like that, third parties made good games with simple controls and interfaces... glitches and bugs only appeared once for a while when you tried to go off the limits of the scenario and stuff like that.
the only non-nintendo console i had was a ps1... I had fun with it, it wasn't that charming for me, neither for my family... but I remember playing my first 60+ hours game (ffix) there as well as playing some medal of honor with my dad, but the loading times were awful... and sometimes the games freezed because of the scratches of the discs... anyway.
I hope the wii u does well, it's painful to see glitches and bricks and stuff but, I think it's normal since nowadays consoles have OS, have online features, etc. At least they always try to do the best they can, delivering updates and fixing your console for free if it was their fault.
