Cons: Don't see any cons, this lens is just perfect - okay, the finishing could be better. Even in a non professionel use and very carefully handling the coating could be scratched! It's made out of MG-alloy, totaly different to the other Ls with plastic fantastic. In wintertime the barrel feels very cold ;-)
Pros: Very good build quality, even a good handling without tripod (could be used for a whole day on a walking trip, not a problem for me), very good resolution on the 7D, even with a converter! 2.8 is totaly usable, stopping down to 3.2 breaks all expectation.
Summary: Don't see any great disadvantages to the new 300 2.8 IS II, maybe less CAs by using it with a TC and the 7D (pixel pitch), maybe more resolutin at 2.8 - but there's actual no need for it. The new 4-stop IS seemed to be not worth to spend more money over the new model.

Cons: none if you have the money but you really get what you pay for!
Pros: sharp even wide open, great with TCs, bokeh, colors, AF, build quality, the lot
Summary: The best lens I have used so far. For animal photography you may want a longer lens but this one is relatively easy to carry and you can handhold it for a long time. It's actually pretty useful for "normal" photography too. Portraits, close ups, landscape...
