Don't think they can do that at this point but yes that was an argument of mine early on.
If they're crippled by the population numbers during an EA, which tends to much lesser than that of the actual launch (y'know dem last minute buyers), I am loathe to consider what will happen then come Tuesday. It's one of the reasons I was hoping to get a bit of a proper head start before the shit REALLY hit the proverbial fan.
Now, we may all be waiting a good long while before some sort of stability is actually managed.
