How do you know it's a great game if it's not out yet?
Unless you are in some closed beta which means that you're breaking the EULA.
I sense another SWTOR. Over-saturated target market, (aka yet another medieval MMO), not the best idea either (Skyrim with people!... but no mod support). So okay, I won't be surprised if it will do well, but my bet is that it will be forced F2P fairly soon after launch. At the end of the day, remember that this game has many many competitors already in the market. It has an uphill battle at the very least.
