What makes you think he won't?
I believe it will be "status quo" for now until they decide if the "War Online " series is worth the effort. I highly doubt you will see ANY work done on AH other than bug fixes, if that, depending on the bug.
AH will take a back seat to the new game for awhile. 3-6 months to see if there is interest in War Online, if there is , you may see other versions come out ... Europe, Eastern front, and so on. Figure a month to setup each, another 3-6 months to see if it warrents a new addition.
I dont hold anything against HTC for expanding their business model, but I dont think it bodes well for AH. I think, being a small company, HTC will be busy putting all of their time and energy into making the new game work. Should the new series of games prove to be a good money maker I dont see ANY time or effort being put into AH. HTC has NEVER been big on making changes in AH. Small changes here and there, but for now I dont see anything coming along to work on tweaking game play, or adding new players to AH. AH will limp along until HTC decides not to bother hosting it any more. Should the new series do well it may be sooner than later.
