I have to worry every time Adobe makes an acquisition. Seldom do the products improve.
Likely it's not accidental that there's essentially no competition in the professional graphics software arena where Adobe products dominate. This acquisition gives the appearance of Adobe trying to maintain its monopoly, and I'm inclined to think it's not really a healthy development.
EDIT Changed Illustrator to Flash Professional. Forgot which was an acquisition.
(I know, because I saw them with my own eyes. ;-)
There were public betas available about 6 months after the acquisition, which didn't leave Adobe much time to change anything. Even the main APIs, like those in playerglobal.swc, almost all have a copyright stamp of 2005 in them.
