Just got that in a lovely email from Trion Worlds this morning.
The full game (regular boring white-bread edition) for $9.99 USD and the Collectors (ultra-super mega awesome edition) is $16.99 USD now until 6/19/11 (that's this coming Sunday)
The trial's fun enough so I think I'll be grabbing this ASAP.
This seems to be a TRIAL upgrade to the full game for super cheap. The slightly less cheap version can be found here
It's 24.99 USD for the Standard and 31.99 for the Collectors. Still a good deal. Though if you have a trial account, the upgrade should work. I think.
