It looks like DICE is already working on a proper sequel to Battlefield 3. The Origin listing for Medal of Honor: Warfighter mentions Battlefield 4 in passing.
The listing mentioned that pre-ordering Warfighter will get you exclusive access to the beta test for Battlefield 4. There was no mention of the timing of the beta. EA has since edited Origin to remove the reference to BF4. They probably swore a lot while doing it.
"BF4? Maybe one day. Remember, if it’s not on Battlefield - The award winning franchise from EA / DICE it’s not official," said the official BF Twitter.
A new Battlefield in 2013 doesn't seem unrealistic. EA has stated on numerous occasions their intention to unseat Call of Duty in the shooter market. In order to do that, they'd need to release a new shooter every fall like COD. I guess they're looking to turn Medal of Honor and Battlefield into a tag team.
The idea of more frequent Battlefield sequels might not be pleasant to some series fans. COD's annual schedule has arguably led to some same-y sequels with little to no upgrades. However, EA knows BF is one of their hottest properties so they're naturally going to try to maximize their profits from it, for better or worse.
