SW:TOR goes partially free to play

EA just announced at E3 that SW:TOR would be free to play from levels 1-15.

Will this help BioWare pick up all the subscribers it’s lost? World of Warcraft went free to play from levels 1-20 last year, but I don’t think it’s helped Blizzard make up the subscriber loss it suffered after everyone finished the Cataclysm end-game content. Seems to me that SW:TOR needs to spend more time developing new modules and content instead.
