There's not one title on any of the next-gen consoles worth buying an entirely new console for. Until you've got a GTA or other major franchise blowing us away (Maybe Watch Dogs?) as Matt says, you're money is best saved for other things. All of the titles on PS4 are simply up-sampled versions of PS3 titles*. They look slightly prettier, but not worth the investment on new hardware. Basically, like "3D" films... you're a sucker if you think you're getting a better experience.
...for now.
The idea that someone would be getting rid of their console because DBC14 hasn't released yet, is insanity in the membranity.
*I'd even wager a bet that there's no titles on the market yet that were exclusively built on dev kits for these new products are, basically, souped-up versions of PS3 dev-kit built games. Maybe, again, titles like Watch Dogs but I think the surefire sign that developers aren't 100% on their games yet is the simple case of them releasing the exact same game on both PS3 and PS4 discs. Until there's an exclusive title, it's not worth the upgrade.
