I'm likely to get both PS4 and Xbox one eventually but from my perspective there isn't enough to justify either purchase. The xbox one price is also ridiculous for the perfomance on offer. I'd play the waiting game until there is a decent catalogue of games available for both and that's proper games that exploit the hardware not tarted up last gen games that basically play the same but uprezed and graphically improved.
My best gaming bang for the buck list would be;
1. PS3 (huge number of great games including some awesome exclusives and more jap games)
2. Xbox 360 (a huge number of great games, outperforms ps3 for most multiformat games slightly)
3. PC (modern entry level pc still capable). Next gen performance, incredibly cheap games. Just the initial cost of the PC as drawback plus not just a slap in a disc and play solution.
4. Wii u, a handful of great titles plus provides hdmi output for older wii games. Probably needs to be cheaper than current to justify purchase with a very limited number of software releases and very little third party support. Third party games normally perform below 360 and PS3 anyway.
5. PS4. The console of this generation. Quite a high price and limited software range. Not the best time to buy.
6. Xbox one. compromised design that can't match ps4 performance, unlikely to get japanese games. High price, low performance and live essential for functionality. Very poor value.
