Yeah who knows if they will but I just found it interesting he said "at the moment" so we will just have to wait and see. It's not going to sway my decision either way on purchasing the game but it would still be nice to play it a bit.
Look at the date of that post, 9/29/2011. Caspian was only available for like a day or two for the PC before the servers were turned off. Doubt they are going to release Caspian with only 5 days left in the beta.
