I don't think they'll try with another AAA NfS. Probably some mobile game or f2p multiplayer crap. Pretty much end of an era (I still have NfS1 for PSX), but they can blame themselves by releasing mediocre or simply bad racing games on a yearly basis.
Meh, after having been playing The Crew over the last month EA is going to have to put a lot more work into an open world NFS than what they have been. Also doesn't help that the last two NFS have been underwhelming IMO.
