Imo, right now It is important, actually extremely crucial to the MMO genre that these games do not fall like Swtor. Because if they do, it is very possible we may not see/very sparingly be presented with new MMO titles in the future.
Regarding to first: Skyrim is not an MMO but people want to comapre Skyrim to ESO in every aspect. So if they choose to do so, I think in this department I think ESO gets a bonus.
I'm not pre-ordering, I prefer to wait for the MMO and see how it turns out. I would prefer $60 up front or $15 subscription, but not both. I am interested to see who is wrong about the future of ESO. I am one to admit I don't know but many people seem very sure of themselves.
