This has nothing to do with "turning your back on the community". Truth is that the community isn't big enough anymore to make it worthwhile
for MS to invest money for (comperatively) so little in return
for them. Ask yourself this: where would all those add-on developers be if MS hadn't invested in the development of the base program? Flight was a (desperate) effort to get the punters interested in (civilian) flight simulation again. It is not MS that has turned its back on flight simulation, its the (mass) market that has (and did so long ago). And instead of gloating about the demise of Flight,
that's the thing we should be worried about: the world at large apparantly doesn't give a flying **** about flightsims. The failure of Flight only confirms what MS was probably expecting. MS most likely will now turn its back on flight simulation(s). And given the state of affairs, I can't blame them for making that sound business decision. They're not a charity. As for Prepared, we're still to see
if and under what conditions Lockheed Martin will (be able to) develop it further. IMHO, Prepared at the moment is nothing more but some vague promises by LM and a desperate clinging on to hope by the FS-community.
Just my 2 cents
