I read that eRCP 1.0.02 Released, now also with support for WinCE 5!!
More information about this Eclipse project at the eRCP project home
I am waiting for next release, eRCP 1.1 which will add support for Nokia's S60 platform.
It is close, the release plan (I think I don't know) for eRCP1.1 is July 2007.
