Doubtful you'll see any new hardware platform any time soon. This summer the 2006 edition of the OS is coming out with VOIP support, IM if I remember right, and a few other goodies. I'm still a firm believer that the current specs can handle most things and that 2005 is inefficient in a lot of ways. My bet is that a lot of the feedback (well, useful feedback) has been analyzed and the Maemo developers are working to improve some areas.
