You're probably right about that. They kind of shrugged off that question when 5.1 came out (although it turned out not to be an issue). If Captain Sim finds a golden egg in MSFS2000, good for them. But it would be a shame to see the P3D goose die. Even if it is more like our old hen Ginger, who still manages to lay an egg once in a while despite her advanced chicken years. Anyway, that's all speculation and it probably doesn't do any good to go in that direction. I'm pretty happy with what I have, as long as they would finish the 737-300. (I've literally run out of CS P3D products to buy.) I think they should do that for loyal customers who invested in a prerelease product, which strongly implies a "released" 1.x product in the foreseeable future. But I suppose my topic title wasn't clear enough. I have not upgraded (I just don't have problems with v.1) and won't until I know that all my CS products work just fine in P3Dv5.2. So I'm waiting for reports that v5.2 didn't break any CS things before I make the move. So if someone did go to 5.2, please let the rest of us know how it went as far as CS airplanes go.

I don't feel CS will completely abandon P3D...but as long as there are models to move into MSFS, P3D products will remain on the back burner.
I honestly thought the other models would be popped out into MSFS faster than what they have thus far, figuring the 777-300 would at least be out by now.  Not sure what the delay is, but regardless, the revenue stream from the base 777 was undeniable as compared to any P3D release, and I can't see CS moving back to the 737 or 767 for P3d because there is hardly any revenue for that.   
The impulse buyers for those products have paid, I'm sure sales dropped off sharply after the initial hype, and the complete stoppage of any progress since the "Belle of the Ball" popped on to the scene also has deterred any others "on the fence" to hold off until CS proves they will continue development.
So with those parameters in place, its easy to see why CS has no real motivation to work on P3D items that will only bring in minuscule if any additional revenue, when there are 1000s ready to pay $30 for each model they pop out.
Well...not sure how CS will market and price the "expansions" to the "base" models, so maybe the 777-300 and 777F will be "expansion" prices, so maybe not $30 for "every" model, but certainly $30 per new base model for sure.  I asked CS how he was going to price the the expansions, no answer.

Anyway...unlike the 777 for P3D, which was truly abandoned when P3D updates came (which they always will), I think work on P3D products will eventually pick up once the MSFS revenue stream dries up.
I highly suspect that unless ALL the current P3d/FSX models have been converted to MSFS this year, CS' official statement for the 767F and CF6 as "Hopeful for a 2021 release" will morph into a "Hopeful for a 2022 release."   That is the only plane I'm interested in, so I "hope" it is ready by the end of the year.
