Google docs and Google wave

Hi all,
I think Google Docs is too like Google wave for wave to flourish. Two people can edit the same thing at the same time. It makes me think that perhaps Google Wave's problem is that it's another offering, which has too much of everything else. Everyone can simply use what the used before as opposed to trying something new. I have used google docs a lot and it has a lot of the same functions, like two people modifying something at once. Its also got the advantage of being more trad.
