*shrug* I think either one of them would do well enough if when the WiiU comes out they also time a universal price drop of $10 on their games.
That's a joke. A game price drop will never happen. Did you forget about the Game Industry Deathwatch thread? The guys that are even making money now are doing it by pumping out sequels. Which incidently is one reason why many companies want new consoles, they want to create new franchises.
A 2012 timing for a PS4 or a Xbox3 just seems too early given all the news of sales and stuff. It seems that the PS3 and X360 have enough life in them for a good 1-2 years before the next upgrade. Then again, it does make some sense for Sony publicly to say they have a new console when Nintendo has one as well.
On the last months sales chart Wii beat the PS3. In 2010 Wii still outsold the competition in both Software and Hardware even in the US.
The "Wii is sucking and the hd consoles are doing awesome" meme just isn't true.
We have a situation where Wii has lapped their opponents and now that its reached them again it slowed down to about match their pace. When the the opponent edges ahead of Wii slightly for a little while they aren't doing well.
The xbox and ps3 also aren't going to suddenly magically increase their sales every year now, especially when a new system comes out with apparently better graphics and a new hook.
I think PS4 is unlikely for 2012 simply because we haven't heard much about it and I don't think Sony is big on keeping secrets like Nintendo. I expect PS4 to be out in 2013.
Edit: On a completely unrelated I don't want to start a new thread for, how reliable is the PS3 hardware? I've been thinking about picking up a used console cheap and I'm avoiding old 360s for the obvious reason.
