It seems very obvious that the devs finally reached the conclusion that the full-featured game was just going to take too long to complete. Oleg stated last year that the game had to be released
in 2010 (!) for financial reasons. They need to get some return on their investment.
Given that reality, decisions on what could be left out of the initial release had to be made. With limited time to devote to finishing and polishing a sub-set of features to release standard it seems that quite a few
non-essential elements have been postponed - DX11 and the dynamic campaign being the two we know of so far.
The approach is entirely logical. I don't think there's any doubt that in time we'll get these features.
1. Possibly not
2. Quite the reverse - we would be much more likely to get a poor quality version if they'd tried rushing it for the March release.
Their strategy is to focus on the essentials for a releasable game - bug-fixing, flight models, AI, terrain
, etc, etc.
Would I prefer DX11 and full dynamic campaign at launch? Of course. But not at the expense of flaws and bugs elsewhere. I think we'll get a solid game initially, with a lot of upgrades to look forward to in the future.
