What we need to *realistically* look at is what big features that
aren't going to make 3.0 now will be able to land later without ABI

Hmm?  Features would obviously land on 3 first, then get backported to 2.

Can say davidz's RI stuff land post-3.0?  Can "Full support for MPX
and multitouch devices."  Can "Revamp/rewrite the entire theming

I think the answer to all of those is "no".  While I know some MPX
code landed, as far as I'm aware none of the widgets have been updated
to possibly take advantage of it.  Do we really believe that we can do
that (easily) in an API compatible way?

So, I think we agree!  2 years sounds fine to me.  However - and this
is important - we really should avoid putting Linux operating system
constructors in the position of possibly shipping multiple GTK 3.x
versions.  This means we need to communicate to application authors
that they should be willing to *stay* on the train if they hop on.
