Download speeds are still a problem for many of us. To put it simply, for many of us PSN download speeds are far slower than Xbox Live or Steam. Yes, some people seem to have fast speeds, maybe they're just lucky to be located near a server, but many of us experience rather mediocre speeds. I'm lucky that mine are just meh. Not terrible, but not great. Sure this could be improved with new servers, but Sony's had years now, and things really haven't changed. This is clearly something they need to work on, and I don't believe they've promised it will be anytime soon.

The PS3 store got redesigned for a third time, and usability regressed dramatically. To me this is a real problem and it happened so recently, and it's a pattern for Sony. Sometimes it feels like they don't learn from the past, and that concerns me for the future. This new store has a ridiculous boot up time, and using it is basically a pain in the ass. Yes, it looks prettier, but the old store was fine, and much faster.

Achievements are going to involve, but we've heard nothing about trophies. Like it or not achievements blew up last gen, and from everything we've heard so far, it sounds like Microsoft intends to push them even further with the XB1. Dynamic achievements, and special events where those who participate will receive a special unlock all sound like great ideas to me. Sony has said nothing on this front, and I wonder if they'll be left behind once again, trying to play catchup in this highly popular sub culture in gaming. On a side note, will trophies still have to be synced on PS4? They do on Vita, and it feels very old fashioned to have to manually do this when the 360 has been auto updating achievements in the cloud since 2005.
