Fast 35 (L, Zeiss or hopefully Samyang?)
Wide shift (OM 35 or otherwise?)
500mm f/4L IS

Samyang 85/1.4 is enroute from Sweden...

My list gets divided into "serious interest," meaning I will pick them up eventually, and "want to try," since I've never shot with them but am open to the opportunity should it arise.

Serious interest:

Leica R 21/4 (I thought this was going to be a CV 20 when the EF mounts arrive, but I shot with an acquaintance's Nikon mount and like the Leica more)
Canon 45 TSE
Leica R 90 'cron ASPH (just waiting for the right copy at the right price)

Want to try:

Zeiss 85/1.2
Leica R 280/2.8 APO and the 1.4 extender
Zeiss 18/4

CV 125/2.5 Macro
Zeiss 50/1.2 100 Year edition
Leica M9 and [a whole new list of lenses goes here]

That's about it
