Out on a limb with this, but I assume you're saying that; sometimes you need to gamble and take the risk of losing? I do agree with the concept, but not when it involves a party I do not know (aka not Blizzard, not Valve,...) or that I absolutely do know (EA). In this case I don't know them. All I see is a game that basically took wow and replaced its roof, but left the foundtion alone (so you might be looking at a new bedroom on the attic, with a nice view on your neighboars wall), which virtually means that everything that's currently in needs to be able to compete with WoW and win.
It's definitely going to be tough for them. Based on that prospect, I'll await "popular" opinion after a months time or so. Even I don't just keep spending my money on games.
