Personally I don't care what its classed as, an MMO, lots of instancing, or single player only, being bioware, starwars and heavily story driven I'm fairly sure I'll love it.
I think I will like it, I generally like story driven RPGs. Its merely a question of whether I like it enough to warrant a monthly fee for it, or whether I end up thinking there are other games out there which do similar for free. The factor in that for me will be whether its got enough MMO in it to warrant an MMO fee.
