Is the US next for a price increase?

Update: I just updated the price watch section and I noticed a slight price increase across the line compared to the last update two weeks ago. This could be just a post-holidays adjustment.

Nikon price increase is already a fact in Canada, UK and Australia. Is the US next?

I do not have any information for now, this is just a pure speculation and an analysis based on the currency exchange rates from the past 12 months:

CAD vs JPY

107 -> 75 = aprox. -30%

GBP vs JPY

212 -> 138 = aprox. -35%

AUD vs JPY

100 -> 60 = aprox. -40%

The above three countries already got a price increase. Here is the USD vs JPY graph:

USD vs JPY

110 -> 90 = aprox. -20%

Do you see the pattern here? The percentage drop in the US is not so big compared to other countries, but it is still significant. Is the US next for a price hike if the USD falls to -30% vs the JPY? Is 30% drop the threshold? Is there a reason why Nikon should NOT raise prices in the US? What do you guys think?
