Not likely to get any more "big name" aircraft in P3D unfortunately.
Looking at what outfits like PMDG have publicly said regarding the market size for the various sims, MSFS seems to be where everything is going. Will likely have to move to MSFS at some point, but for now, I guess I'll just be happy with the FSLabsA320 and Majestic Q400 in P3D to satisfy my flightsimming
