I agree the cost is a little high, but it FF! If you have seen or read anything about it you would know that it is going to be sweet... and as for lack of interaction, there can be up to 10,000 users for each server and 20 servers... they are expecting it to be huge, and I don't doubt it will be. and if you think it'll disappear after a few years, look at games like warcraft and starcraft... they have been around for quite a while and there are still servers set up to handle those. Sure they may shut down a few servers, but as long as there are people playing then there will be servers.

Oh and as for $10 a month... I make more than that in an hour of work... its not a lot of money for entertainment. How many games do you rent a month and how much does that cost you? Do you go out to see movies, or maybe hang out at an arcade for a few hours? $10 people, its chump change...
