Google Wave - Logo thoughts

I am as excited as everyone else about Wave.  I wonder though why they went with a Google-y logo (rainbow colors) on thier API page if they want this to be open and have other ISVs implement Wave protocol?  It's a really cool logo, but I think they should have went with something non-Google, as they did with Android.

I can't wait to get my hands on this API though... as soon as school is out I'm looking into it.
