I generally agree that Estes will not likely resume making kits that require composite motors, at least until they come up with a way to make money selling composite motors. From everything I've heard over the years, what @Scott_650 says is exactly true: the PSII kits didn't sell well, which is why they were all clearanced out and discontinued. Remember that "sell well" for Estes is quite a different thing from other companies; they operate at much higher volumes than everyone else.
So I too would expect to see more kits that are designed to fly on 29mm E and F motors. It sure would be great, though, if they could come up with a higher-thrust BP motor, to handle heavier rockets. I don't know if that is in the cards at some point.
And speaking of the Es and Fs, lately I am frustrated their lack of retail availability. In my neck of the woods, there's no place I've found them, since Hobby Lobby stopped carrying them and my LHS (which really doesn't have a great selection of rocket stuff to begin with) doesn't carry any of the hazmat motors. I don't use enough of them to justify a hazmat order. This may not be an issue for HPR fliers, who already have to deal with hazmat on other purchases (sometimes, at least), or those who have a good vendor at their club launches. But for the LPR hobbyist who wants to move up in class a bit, it's an obstacle.
