Good point Alex; the aircraft sim DCS does a good job of this (for Battlefront's reference): https://www.digitalcombatsimulator.com/en/news/2018-07-27_YAK52/
They just lay out some of the things they are planning, generally to work on, which I think people interested in whichever aircraft is being discussed, find interesting, and gives them the sense that work is progressing - especially when, like these games, it might take one or two years before the product is ever seen.
Below is an example of one of their updates:
Complete the AIM-7 with addition of FLOOD, Home On Jam (HOJ), and LOFT sub-modes.
Integrate AIM-120B/C for STT employment (TWS employment will come later).
Integrate AIM-9X Block I. This includes both flight dynamics and new tones. Afterwards, in August or September, we will add the Joint Helmet Mounted Cueing System (JHMCS).
Complete RWS air-to-air radar mode with such features as Non-Cooperative Target Recognition (NCTR), AACQ mode, Latent Track While Scan (LTWS) mode, Pulse Repetition Frequency (PRF) settings, ability to change radar settings with TDC along outside of radar tactical area, radar speed gate setting, COLOR option, and more.
Complete radar warning receiver functionality with contact symbols and modifiers, EW HUD, and the OFFSET function.
Integrate Paveway II series laser-guided bombs (GBU-10, 12, and 16) with JTAC designation.
Further tuning of flight model with touch and go performance, gear drag, half flaps drag, takeoff pitch characteristics, and extreme angle of attack performance.
Brightness control for the HSI display.
Multiplayer carrier deck spawning issues.
Wingtip vortices errors at low airspeed.
