According to some articles that have been found since the announcement, the factors like player retention etc would appear to have been of little import in this decision (CoH's performance was pretty 'flat' since Freedom launched, neither up nor down compared with others in the market who've been losing players) - what appears to have happened is NCSoft took out a massive 111 M Won loan, bought some stuff, sold a chunk of the company and found themselves looking at a $6M overall loss on it all, and something had to give. All their eggs are in GW2 and Aeion, and they are focused on Asia as their primary area of business: if anything was going to go to clawback that $6M it would be something they didn't expect to see huge returns on during the next quarter and whose core customers were outside Asia. Unfortunately CoH fits that bill.
