I think some of you are making this overly complicated. The 4.09m final is just an interim step until AAA and our techies figure out what has to be done to get us to the "final solution". We will still be flying mostly with the current switcher on 4.09 modded.
IF you want to install the new 4.09m final patch and fly some of the new aircraft, all you need to do is install it over a clean copy of 4.07m, the 4.08m patch and add the no CD crack. All this stuff is in the vault. Waiting until the dust settles ain't going to buy you much.

As far as the new skins are concerned, they are simply optional for those who have to have everything.
