Great to see the useful discussion going on here.  I hope my 
contribution is helpful too!

Reviewing these kind of options is difficult in isolation.  But cost / 
timescale / target market asside my personal instinct would be to keep 
changes for the next phone super simple: a glamoectomy and some cost 
savings - gta02.5 maybe.  Save the new ID for a later device, targeted 
further in the future.  But whether a 02.5 is sane would depend when it 
might enter MP.

Now the buzz / bass problems are understood (fixed in new designs?) The 
Glamo seems to be the biggest weakness in gta02 - affecting UI 
responsiveness, 'wow' and software development of funky new stuff.  We'd 
need a changed interface for the wifi (iirc), but from my non-expert 
position it seems reverting to the gta01 LCD interface should be low 
risk.  A simple gta02.5 should have a highly predictable schedule, and 
allow the new s/w stack to shine, with minimal software re-targeting 
needed.  If we kept RF & case designs from gta02 does that make 
certification easier?

gta03 / gta-future would then be (a little) further reaching, +p +e +cam 
+ new ID +external SD card, and aimed at better defined 'consumers'.  
With more lead time, this is the one I see the community getting more 
involved in designing - identifying the target audience, appropriate 
parts, roughing out schematics, exploring limitations, rinse and repeat 
of paper designs until OM are happy that it's buildable.
