I think the updates are the real issue and headache for developers as far as SE or P3D is concerned. I can't imagine devs being able to "keep up" long term and actually turn a decent profit with 3 versions of the same sim all needing different updates at different times to kick out the same product. Seems like insanity to me from a ROI standpoint. I'm definitely going P3D route no questions asked. As for FSX, I won't uninstall it, but I'm not going to get SE as my legacy FSXA discs are all in perfect shape. From my POV, it seems that LM will be making updates and long term investments into P3D, the kind we've not seen and only heard noise about until now. Considering it will be it's primary sim platform for commercial use, seems like a good wagon to be jumping on to. That's where my time and money will be going as far as support goes. Not that FSXSE is isn't probably a great platform, it must be, with 200K DL's. I just know that my P3Dv2.5 install is flawless right now...it's like ACES got together and fixed everything that was supposed to be fixed and introduced the great new features that would have been FSXI. Once TacPack Premiers later this year, for me, there's no reason to make the switch almost indefinitely.
