Suspicious.....M$ Xbox One's price was announced 1st for $500, Sony makes it $400. Then M$ release date is November...Sony's is 'holiday 2013' which could mean Sony is waiting for M$ to announce their exact date and then Sony trolls M$ by releasing PS4 earlier than MS. Possibly October...and now this! lol MS said their limit was 1000 friends now Sony announces 2000 friends. Sony sure knows how to do business.
Theonline and offline notifications would be non-stop with 2000 friends... but i'm sure you could group your favourite friends and keep notifications limited too them.
