I think it's very interesting to note how long this game has been in development, considering it's neither CoD nor Duke Nukem -which WILL be released next year by Gearbox who now owns the IP-. They -Maddox Games- must have relatively low burn rate since the IL-2 series is by no means is a triple-A series of games.
Whoever their publisher is, they must have A LOT of confidence in O-Team. Everybody's saying Ubisoft is the publisher but I find that hard to believe since Ubisoft since a while back has stated that their main focus for games are in the console market -piracy- and rather then bringing out many different IP's they'll be focusing on a smaller range of triple-A titles instead i.e Assassins Creed.
Oleg and his team is a dying breed IMO, game studios have more money then ever but the sales of the games not only has to match the expenditures but also produce waaaay more profit if there will be any sequels/second chances. This is where DLC makes it's entrance me thinks, forget about expecting free patches with additional content, those days are over. A lot has happened since the first releases of the IL-2 series. Bug fixing patches will be free of course but expect to pay for all the other stuff, planes, map packs etc. Finally Oleg can actually make some money from us cry babies
I'm more then happy to pay for stuff coming out of Olegs team because I know it's always top quality. These are just some educated or less educated guesses IMHO
