I think they should have held off till 4k could be done at 30fps on new hard ware. I had in the passed posted that new hard ware should wait till 2014 or 2015 if possible.
I feel Sony put out good enough hardware that they can run with it. MS just shot themselves in the foot to many times.... this comes from some with xbl from day 1, and about 70 new games on the 360.
really a 500 gb hard drive non-replaceable with the original sharing/always on install required original plan what were they smoking game sizes have gone up to what 25-50 gigs a game so at best 20 games installed? they could have made it user replaceable so i could drop a 3 or 4 tb HD in the system. my launch 360 has been upgraded to a 250 gb - the 20 lasted until 09 and the 120 was good through 12 when i needed more storage, only required installs on these drives and dlc.
and the gpu I still cannot believe how much gpu they sacrificed, and how old the tech was compared to gpu on market . when you look at the 360 vs gpu on market at launch it would be consided just under top offered gpu with features not found in gpus till next generation. where as the one has a modified gpu from lower midrange from a year before it came out wooo.
note i did not expect a 7970 or a r9 290x or a gtx 780 ti, power consumption is just too high, but something better than a 7850-7790 range gpu, or carry out a more customized core.
all i can think is AMD must have cut both companies a very sweet deal on cost. and Sony made the right choice MS did not. The the MS policy team decided to drive the brand into the ground with ill concived choices for the current market.
