Ok to answer these...
-Lack of updates.a Xbox One had 8 great updates and PS4 had one boring stability update
So the only thing that matters is the number... Most people are not clambering for an XBO because of its updates. Thats not to say they haven't added some nice things, but for a PS4 only user at this time, I don't think...hmm forget the games I am playing, I would really like to snap TV and Trophy information while playing... I don't, because i didn't want that feature to begin with.
-Lack of Exclusive games, PS4 has no more this year other than Drive Club which not that many people want. LBP3 is on ps3.
Ironically they have about the same exclusives, but some on the other side seem to think that MS have way more. You know what I would rather have LBP3 than Sunset overdrive.. and I really do think SO will bomb hard.. so there you go, we shall see what MS owners say about MS exclusives when it gets towards Xmas, I would even go so far to say that I expect TLOU to sell more than SO.
-No longer the king of indies. Xbox One has more indies coming in Q3/Q4 this year.
All lists I have seen, Sony have way more games coming out... link please to all these games.
-Lack of 3D blue ray support
It's just been implemented... bit slow to the party mate.
-Lack of Youtube uploading
Yeah this would be nice. But doesn't stop me from playing games.
-Lack of Full HD twitch
Yeah this would be nice. But doesn't stop me from playing games.
-PS4 no longer has price advantage over the Xbox One (who can blame sony though)
It doesn't have the price advantage but it still has the performance advantage, and some may disagree, it also has the better build of the two machines.
-Sony basically told EA to buzz off and that EA games had no value
... many people believe that EA doing this will lead to a Ubisoft service and a Activision service...etc etc. One stop shop is always the better option. If you like EA games, then buy an XBO to get those features. Sony has every right to say yes/no to an offer from a games company. Perhaps if MS had said no to EA at the start of this gen, perhaps they wouldn't have got lumbered with their DRM policy (which lets be fair was born out of a similar idea).
-MLG went to Xbox One instead of PS4
MLG will do nothing for the fortunes of the console... Pro gaming right now is all about PC. Console gamers can also own PC's... so strangely enough this does nothing... except for those who might like MLG access it from XBO.
So yes some of those things are useful, but really don't mean anything to the actual thing thats important for a console.. i.e playing games.
