If I had my time again I would buy the PS4 - cant really understand why you've bought both?
For my money I wouldnt buy a XBO for 1/2 years - wait for a backlog of decent exclusives then get it. Chances are there will be some more exciting things in the pipeline. All IMHO of course...
Arguably you could say that about either console though? If anything Titanfall is the only next gen game coming out soon which might encourage me to upgrade.
I'm still undecided - the only One exclusive I know about which I'm looking forward to is the next Halo - other than that all the other games I want are on both formats.
I'm still enjoying BF4 on the 360 and with Dark Souls 2 and Titanfall on their way (although appreciate the latter might not be great on this format) I won't be making a change for a while.
