Cannibalization is not the norm. There are many successful platforms which didn't go the route of cannibalization. Ex - windows.

The OS 9 - OS 10 example is more of an exception than the norm. In the case of OS 9 everyone(even Apple people) knew it sucked big time. They tried hard for several years to fix it's problems or try to develop a new one. There was no way for them to continue with OS 9.

RIM isn't exactly is in such a bad situation. Agreed that they need to woo developers much much more to their platform but that doesn't warrant cannibalization. They should continue innovating but should be more evolutionary.

The bad thing is that for a long time RIM sat on it's laurels without much innovation. Good thing is that they still haven't lost the market share. They already moved from their strong place of qwerty keyboards to touch screens. Much more innovation is needed. Not just copying others but having a vision of the future and then aggressively executing on that vision. They did it once before which made Blackberry such a cracking brand. Now they should do it again.

Eh, even Windows could be argued to have followed this pattern, with Windows NT. Different foundation. They did end up supporting the 9.x APIs on the NT platform, to create Windows XP, but the fact is they still released a “competing” version of Windows first.
