So for those of us where it isn't obvious what the 4 lenses might be - in decreasing order of likelihood:
1) Non-L 50mm IS f 1.4-1.8 to replace the venerable 50mm f 1.4
- With the pancake 40mm, and the nifty 50mm, do they keep the 50mm as is or make a little refinement to it too? Could they do much for the price?
2-4/5) Successor /replacement to the 85mm f/1.8, 24mm, 28mm, 35mm
