ME3's single-player DLC was shelved so that the ME3 single-player team could work on the Extended Cut. Now that EC is out, we should be seeing regular single-player content sometime in the near future.

And I don't see how SWTOR's falling subscriber numbers have anything to do with it. SWTOR and ME3 were made by two separate studios within BioWare. Even if SWTOR isn't revived when it goes free-to-play, its failure shouldn't have any effect on content production for ME3.
