Doubt it's true since they would rather look at your PC specs, their not going to let someone join the Beta because They said #gw2Beta. I don't trust this one.
Well, assuming he's telling the truth, it gives members of his fansite forum guaranteed access, rather than FFXIAH players. I see there's already some responses with just one post.
It could just be a cynical attempt to get a lot of hits on his site for the advertising revenue.
his argument is that Cliff worked on FFXI and on GW2. And because of that FFXI can get access to GW2 beta on that forum. If it was that simple id expect ANet to hand out guarenteed invites to GW1 players aswell. I mean come on, alot of developers who worked in GW1 work on GW2. And thanks to the boxsales from GW1 they can make their sequel.
And since i havent heard anything from ANet about letting anyone with GW1 into the beta, i highly doubt theyll guarentee a spot to people who play a completely diffirent game just because they share a developer.
