The image below appeared online today and it would seem to suggest that something Battlefield related will be shown at "The Future of Playstation" event tonight.
DICE boss Karl-Magnus Troedsson is currently in the States showing off, well, probably Battlefield 4, as he tweeted:
"Busy 6 days on the road all over the US, making some noise, making some moves!"
He also retweeted something GameStop boss J Paul Raines posted:
"Got to see Battlefield 4 today and all I can say is WOW! Thanks @EA for the sneak peek. Can't wait for you all to see it. ^CEO #BF4"
The Battlefield series has had close ties with Playstation much in the same way Call of Duty has with Xbox - and it wouldn't be surprising if we saw Battlefield 4 at tonight's live stream from New York.
