Niche market, bad economy. You don't purposely decrease your existing player base without very careful considerations of how many you would possibly pick up.
I'm pretty sure that HTC knows exactly how many players they have running on what type of connections and equipment. Since they have specifically mentioned that some older, less powerful graphics cards (like the Intel Embedded cards) will still work with the new version they are making they KNOW how much they stand to lose if they don't support it....
Unlike games like Eve where the Devs said "We estimate that 97% of all computers will support Shader 3.0 by November, so we are going for that as our minimum video standard" when less than 50% of their current player base was running it

That said, new maps, new "goals", working on ground units, etc gets a big

Just don't equate higher hardware requirements with a better game....
