They did as promised- the most powerful console out there. It will undoubtedly be the best machine for 3rd party multiplat games. Really, IMO their biggest problem though, has been first party development which is lacking, and of course Japan hardly supports the hardware at all, so there really isn't much exclusive to make the platform stand out. Still, great hardware.
I'm actually a little torn, because I will end up with a 4k tv soon, and also also a Christmas bonus with which to maybe invest in a 4k console.
I don't know if I want to get an X (true 4k console, 4k blu ray), PS4 Pro (4k support, if not "true" 4k, no 4k blu ray (boo), but more games that I actually play.
Or, of course, option 3- skip these machines altogether, I'm more or less fine playing games on my existing maches and why invest $400-500 on a machine that has maybe 2 years left, and I'm guessing PS5 is due around 2019.
Part of me wonders though, if PS5 will end up being Xbox One X- like in terms of specs (basically true 4k) and then the X will just become the new standard for the Xbox lineand they will just start making new games exclusive for that hardware and stop supporting the OG Xbox One.
