I for one, look forward to trying the new sim. I am so tired of all the problems and maintenance needed to keep PD3/FSX running correctly. It never fails, you get the sim running nicely and a week or so later something happens, leaving you scratching your head wondering why your nicely running sim is now DOA.
I don't blame the developers for trying to program around the sim's limitations. They are trying and usually do create a better running, flying, looking, etc product. The problem is that when you have a dozen different developers doing work-arounds sooner or later some code from one developer will conflict with code of another developer. Then we, the users, are left scratching our heads.
It looks like the new sim will come with a lot of current add-ons built in. The developers will also have a much more viable and rich set of basic code to build new aircraft, scenery, or whatever is needed. Hopefully, there will be little need of work-arounds.
As much as I am not an Apple fan, I will admit that their 3[SUP]rd[/SUP] party restrictions and control helps their products to work well.
