my guess would be because they put the call of duty maps on sale and there are a million kids downloading them today , plus they are having psn issues with the madden 12 servers unable to connect over psn too
the store actually updated around 11am today , they just didn't post the update or refresh the store interface until later so it wasn't down right after the update finished like some are saying
I downloaded the mk kollection and elevator action at 11:08 am by searching for them and didn't have any problem being signed in or staying signed in when I logged off at 2pm
I disagree, at least in comparison to the rest of the summer updates. There are lots of new games and demos, though only 1 I wanted.
Each to their own, but I agree Summer has been lame PSN wise.
