The poll is a bit hard for me to answer as I'm in a bit of a special situation.
Buying a PS4 to sell for reasons which are a long tale. However in reality I'd probably say none, not even Wii U (anymore) as I'm no longer in the mood to get shafted as an early adopter anymore. Would I rather wait 9-12 month and buy a console with a better initial bundle, where the kinks in the services have been worked out, where the release games have dropped in price by 75% already and there is a decent catalogue of games? Yes, yes I would. Save cash and get more? Winner.
However there is another factor: I have a good PC now. This has massively put me off wanting a new console. It slams the Wii U almost across the board and the multiplatform titles for the PS4/XBone will be on it as well (probably still looking better!) And yes, talking about exclusives like Titanfall, Octodad and probably The Witness. It may have cost me more but I use it for many other things and Steam/Humble Bundle have saved me a shit ton of money already.
