BF4 had an OK spinoff in Hardline but nothing to take over its userbase. Star Wars is going to get milked for all it's worth a with games and I'm sure this won't see any support after the first year when they've announced a sequel.
Sequel won't be announced next year though. March 2017 is the best guess for that announcement. They'll have other Star Wars titles to show off soon and won't need to annouce Sw:Bf2 as early as they did with sw:bf.
Dice has supported all of their games for long stretches, directly or not. I don't see why that would change now. Bf4 is still getting patches and free dlc.
