From what i am hearing, it is US only... but other countries have dropped a bit. I just hope that it drops a bit here in India... I've been saving a long time for my 500 f/4 and would be miffed to buy and then it loose value right away!
Canon India did drop prices a couple of months back. The lenses included in the recent drop were 180 macro, 70-200 II, both L TSEs, 85L and the 300 2.8 II L. The price drop was quite steep, approximately 14% or so.
The superteles. Including the 500 II are already reasonably priced in India. The 500 II can be got for INR 550K. This is slightly less than, or roughly equal to the US price which I believe, underwent a drop recently.
