I've noticed that has been the case on their Discord page too - lots of inquiries, but no answers other than to say that their MSFS 2024 Spitfire is the number one (and possibly only) focus at this time.
Counterpoint: the MicroProse B-17G...
It has been just over two months since the last progress report was posted for the MicroProse B-17G (MSFS 2020 and 2024). It's looking really great, both inside and out:

Also, this update from April mentions that they want to release it as soon as possible as an "Early Access" (first for 2024, and then for 2020):

If you page back through this thread, there are some great screenshots showing the level of detail being placed into the entire interior of the aircraft, including the bomb bay and turrets:

With the MicroProse development, I'm really impressed by the accurate detail of the interior. For instance, most people would probably just depict the whole of the interior fuselage painted interior green (as many restorations and models have been done over the years), where as in reality, other than the cockpit section, the vast majority of a B-17's interior was actually left bare metal. It's so great to see the MicroProse B-17G interior accurately reproduced in that manner, along with all of the other intricate and accurate details throughout. They've also shown that they've recorded sounds from the B-17G 'Sentimental Journey' (the same aircraft that the miniseries "Masters of the Air" also used for their sound recordings). We can only hope that the flight model and systems modeling will be the icing on the cake.
