...P2 in general is a tried and true format used by the majority - but its inevitable it will have to change in the future. Will they be nice and give us backwards compatibility? Who knows, that's how they make $$$.
There does reach a point where you have such market saturation that introducing the latest and greatest and not making it compatible with your previous gear may doom the latest and greatest to failure. Betacam is a great example. Each new version could play back the previous version (or two). Thus Betacam in it's various versions was the standard for what, 20 years almost? P2 is at that point, and got there a whole heckuva lock faster. Panasonic would torgue a whole lot of people off if they introduced a "P3" like Barry has been proposing and didn't find a way to make it backwards compatible.
