This is funny actually! Everyone has a different take on what the situation is.
I think the main thing to remember in making sense of what can seem like contradictory statements is that the sequel process will follow the same strategy as the original il-2 series. That means that advances to the game engine and new aircraft/theatres will install over previous releases but will also be standalone packages.
But I don't believe that previous aircraft were usually included in subsequent instalments (with the exception of il-2 1946)
In the context of the question I think he is referring to carrying work on the COD aircraft over (FMs, etc - the high altitude performance will only be addressed for the sequel - so it will make sense to revisit the COD aircraft then) but I don't think (?) that the COD aircraft and maps will be included with the sequel.
I think he is referring here to sequel features being 'tested' in or 'added on' to COD before the sequel comes out. He said elsewhere that they won't be doing that.
But it really has been said many times that COD will be merged with the sequel. The above quote is needlessly messy and confusing. See the one below from the same answers session:
Quote:
I know you stated the next CloD patch will be the last, so that means any fixes, advances and such into the game engine that come from the sequel will not be translated at some time or another back into CloD? Will Clod be completely abandoned in whatever state the final patch leaves it with no hope small updates, etc?
Why would you think that? We’ve never done that before, and I’ve always stated that our plans remain the same. There were many issues in the original IL-2 in 2001. After a few updates to the original, Forgotten Battles was released and there were no more updates to the original Il-2. That doesn’t mean it was abandoned however! You can still play all of the original Il-2 content with 1946, all carried over and updated with the rest of the engine.

Bottom line - I'm right folks! Trust me. I'm prepared to take bets on this.

A lot of this stuff has come up before. You sometimes have to read between the lines and get the context of quotes that
seem to imply something else.
