Now the NDA has been lifted can someone confirm to this self confessed alt-a-holic the amount of character slots available?

At last beta it was increased from 4 to 8 total number of characters available per account.

There were 8 in the beta. Dunno if that will be the case when it goes live though.

8 last beta, but since it seems volatile, it may decrease to 6 (money wise they make more, 4 sounds too little, 8 a bit too much, and 6 is ideal to make money with cash shop options).

Currently 8 to my knowledge but I read somewhere that they may be 2 more totaling 10.
