I pretty sure of this as well, this is the first free month of a newly released MMO, everyone is having fun but when they'll have to put money in it a lot of people will get back to Wow, War or whatever
Hope so - this past week I have noticed a lot of kiddie WoW players suddenly join....one of the most appealing things so far to be in Aion has been the playerbase...
It's definatly keeping my interest

The queues are really anoying during the week though..loosing about 2 hours a night of playtime to them grrr
