They're doing plenty. It's not always on the front page, but you can find out what they're working on in the forums sometimes.
- 410 research is currently underway (maybe even the work for the flight model?)
- Skins are being increased from 15 slots to 30 per plane. This means going over a year's skin submissions, adding in backlogged skins, reviewing new ones, removing any old ones (including old skins on the remodeled planes like A6Ms, P-40s), sending out e-mails to skinners, etc.
- It's Thanksgiving, and Christmas season is coming up. It's a time when production in most places slows down as folks spend more time with their families. Can't expect too much during the next month. If we get it, great! If not, totally understandable.
- any 3D work/upgrades to older models that is being included in these updates alongside new additions, to finish off the "uglier" planes.
So that's the stuff I can think of, off the top of my head. Not necessarily front page news, but there ya have it.
