Haha I must be the only weirdo who did not find much to love about GW1. But GW2 on the other hand IS looking pretty fantastic!
Will also be getting the Collectors Edition. I usually think buying Collectors Edition games is a waste of cash, but for MMO's it is often very useful longterm (as long as I get some nice ingame items I am happy).
Aion and GW2 are as far apart as Aion and Guildwars 1 were. Aion has more in common with WoW than it has with either of the Guildwars games.
So ... same feel ... absolutely doubt it. It doesn't even have the same development team behind it.
