Maybe, but by the time they do there'll be Yet Another New Damned Flash Memory Format.

Then again, CF is still around so hopefully SD will last at least as long...

Personally I dislike the newer card forms. They're just too damned small!
My fav. form factor is MemoryStick, but alas that is a Sony thing so they won't let anybody else use it.
SD is like MS Duo, which are acceptibly sized.

These newer sizes are getting ridiculous. Seriously you OEMs - Anything I could accidentally snort up my nose is Too Damned Small okay?!?!
