This was the most expensive MMO of all time at over $200 million tossed into development hell. The game launched in a wounded state, unfinished, broken, non-existant customer service etc. The game didn't even have (or deserve IMO) a honeymoon period. It launched and immediately began to hemorrhage subscriptions and never recovered.
How much went into D3? Blizzard made it (and treat it) like an MMO. It has no subscription though.
TOR has to go on losing players and revenue and reputation while they frantically try to get the F2P / P2W model set up. Meanwhile GW2 and the rest are coming out.
Gotta be one of the biggest flat out MMO financial boondogles of all time.
