Is the genre really that risky? A ton of them come out of Asia all the time (granted none of them bother to really innovate).
It is in western part of the world. Most Asian MMOs are based on micro-transaction model, very much pay2win and extensive grind, and they like it that way. Take a loot at most common, single player, jRPGs. They usually are built around the idea that at some points of game you have to just run in circles popping random encounters to level up/get items/get cash, and their MMOs work exactly in the same way. Furthermore the whole micro-transaction model is very much based on peer pressure, which is much stronger among Asian cultures.
This however doesn't work well in EU/NA. People here prefer more refined gameplay, hence even the titles that are licensed from Asian companies are often tweaked for western audience (higher exp rates, higher drop rates, higher quest rewards).
Even then, you have the issue you mentioned - most of Asian MMOs are pretty much same game, based on modified L2 engine/mechanics, and the only thing that changes between the games is the backstory. That doesn't really work in west either. We like more variety.
If you add up all those things and then think about costs of developing MMO, the time it takes to create one, the costs of customer support, regular update, server upkeep... You need a huge pile of money ready for it. Even huge companies can't risk such things.
Look at BioWare with SWTOR, they had great IP that in theory should guarantee long term success, they had money to make it and backing from one of the biggest publishers - EA. Yet even then they ran out of money during developement periods, which led to rushed release, which led to ton of issues in first months, which means now they have to play catch-up to bring the game up to proper state, which causes people to unsub because they don't want to pay monthly fee waiting for features that should be there from day one.
These days, nearly 8 years after WoW release, to really be able to establish a MMO you need something fresh. TSW has it's setting and puzzle based investigation missions, lack of levels and classes and some very interesting ideas mixed in. GW2 has buy2play model with cosmetic cash shop, semi-action combat and dynamic questing. PlanetSide2 will be free to play, with cosmetic cash shop (or so they say) and is actual MMOFPS (as in ~800 people fighting on single persistent map, and not just big lobby for small 10 minute matches). Those are things that are needed now if a company even hopes to not sink after first 3 months.
