I'm willing to bet that if Giovanni does actually get defeated by Ash and decides to disband Team Rocket, the organization will still exist; they'll just pull a second-gen and put the HGSS Execs in charge. The Team overall will probably become a lot weaker and fragile; JJM might be considered high-ranking officers by that point since they're totally loyal to the Team's evil endeavors regardless of how ruthless their orders are. If this happens, I'd expect Team Rocket to be around for at least another generation or two in the anime, until Ash battles Adrianne and Archer and takes them down, too.
I do kind of hope that the Executives at least make cameos sometime in Best Wishes; I've really wanted to see them in the anime ever since they were given names and personalities in the Johto remakes...
