I think one major reason for the delay has been explained by TD:

Development Update - 2010-05-20

Dear IL-2 fans. We would like to inform that after several months of negotiations with Oleg, Ilya and MG/1C management, our team has signed a non-exclusive license agreement. Basically this agreement will give Team Daidalos full access to all assets related to the sim, but our work still remains non-commercial. Most important assets for us now is the SFS tools so that we can build the patch independently and don't need to sacrifice MG team's precious time. Also this will speed up the releasing process, since we can do a new build ourselves if we find bugs from release candidate build.

This past month we have been learning the use the new tools which has taken some time. Also we had to build up a proper codebase for the tools and overall adjust our ways of working. So please have patience and excuse us for the delay. We still do this for free as a hobby and not from 9 to 5 and probably everyone has had less time to give to TD than they wanted to give. Good news is that we don't have any major bugs open. Just some integration work left, finishing some WIP default skins, adjusting some small things and testing that we didn't break anything.

This should help ensure the long-term viability of continuing patches, as 1C:Maddox will no doubt be too busy with SoW:BoB etc to commit further resources to what is after all a low priority for them.
