I'm happy to see that some sites, like Giant Bomb, still have the basic decency and integrity to hold off on reviewing a game until it is final, regardless of when an embargo ends.
If you haven't played a MP-focused game on the actual network that everyone who will buy the game will be playing it on, you shouldn't be publishing a review of that game, full stop. Polygon doesn't know what kinds of issues these games might have online on PS4 or XB1. Also, it is likely that the PS4 version will be getting an update that addresses these issues. If that update is out on day 1 and it fixes the stuttering issues, then what? What happened to the "just wait and see for proper info" attitude that they were all about?
Oh, that's right. Polygon can just "update" their review to correct their rushed and irresponsible reporting and get a whole second round of fresh clicks. If they feel like it.
What a bunch of hacks.
So polygon wasn't really wrong then? Wonder what other sites say.
They are wrong for reviewing a game having never played the MP on PS4 PSN or on XB1 XBL, and they are wrong for making such performance judgments about an unreleased product that is confirmed to have a patch that will address (and hopefully fix) the stuttering issues that are unique to the PS4 version.
And impressions from less biased sources (ones that haven't been personally publicly downplaying resolution differences and belittling those who disagreed, for example) on the differences between today's versions of next-gen CoD have noted some occasional stuttering with lots of particle effects (IGN, Giant Bomb), and a couple other sites have noted that the resolution difference is pretty big.
It would be wise to wait for the game to launch and to wait for Digital Foundry to do their work.
