The drop off will come from folks trying the game and simply not liking it. Showing up for the party they’ve heard about and simply not liking the band.
The AH won’t save it for these people. The market won’t save it for these people. Guilds won’t save it for these people.
They’re going to come in with all these stories, play around with it, and find the stories don’t match the experience that they’re having.
The game did not change and evolve in a vacuum.
As for anecdotal evidence, among the people I hang around with, none are interested in the game. I know one person personally who is gung ho about it, ready to dive in. But I don’t know how long that shine will last, frankly.
The company is prepared for an onslaught early on and expecting a population decline. The entire Layering facility is premised on this.
If populations sustain, then they can create more realms. But the people will have to move to them voluntarily. But if Blizzard felt a collapse wasn’t highly likely, they would simply provision more realms up front.
No, they don’t “know” just like any of the rest of us. None of us “know” what will happen.
But they do have a good feel for traffic, populations, demographics, etc. Lots of folks trapped at desks all day that figure this stuff out.
So, if they think and are planning and tooling for a drop off, then it’s more likely than not.
When Phase 2 hits, and Layering is removed, we’ll know. If there are more realms created, then more folks stayed than not. If not, even if there’s one particularly popular realm, then Blizzard will have felt that there’s enough capacity on the other realms for folks to transfer too, without Layering.
And if they add a RP-PVP realm or too, that’s a different issue that’s not population based.
But, either way, by December – we’ll probably know.
