EA has now said that they'll make a statement before 12.00 PST/21.00 GMT+1 about what they are going to do about the problems. There are several options:

1) Complete rollback to the previous version 1.0, however all users running version 1.01 are a big issue. EA doesn't know whether the patch can be rolled back. Maybe the game has to be re-installed...

2) Small fix to solve the memory leak problem

However, this is all complicated by the fact that the DICE guys are on their (well-deserved) summer holiday and have to be called back to work. Thus there's a risk of further delays.
