Will 'real' versions of FCP stop working with Lion?

I really feel like I dodged a bullet on this one!

I make no claims to be a 'professional', but I've spent many years playing with FCS, trying to learn as much as I can and develop my skills as much as possible and become as much of an expert 'hobbyist' as I can. I WAS looking forward to FCP X and in fact was going to purchase it and the new Motion and Compressor on June 21st when I got home.....but then I read all the reviews and opinions....and I honestly feel lucky that I didn't waste the money on it.

I still have the FCP suite and it works just fine for me (I never even upgraded to version 3 b/c I thought it was a weak release and was happy with FCP 6, Motion 3, and everything else that went along with it)...but now with FCP X out and the Lion OS coming very shortly, I am wondering:

Is it possible that if I install Lion, FCP 6 may STOP working for me? Would/could Apple do that?
