I think it is simply this way:
UBI puts x number of $ to the developers to develop and produce a product by a certain deadline - and by the looks of what carl said, will allow fixing of major bugs.
We saw with IL2 that generally it was in good shape upon release, and we saw with LOMAC that it generally wasn't.
I'd say part of the problem was the developer, and part the publisher, if the developer can't get it done in time and the publisher forces it out then the consumer loses.
There's a lot of little polishing that could be done to LOMAC (adding a phone book like the one in falcon, netgraph to help troubleshoot, adding alternative graphics for those who have graphics cards that can't deal with method the effects were done with, use the workaround for sounds i mentioned to reduce the effects of the problematic sound engine), and some bigger stuff like redoing the mission creation system and loadouts systems that would have generally improved the sim's functionality and made it outstanding.
5 Months later and we're still seeing what is essentially development work being done - and without money coming in to pay to fix any bugs that appear due to this continuing development there's a good chance we're going to get stuck with problems - I just hope these problems aren't going to be the kind that breaks gameplay.
