@oyvoy - You have to put 2 factors into this equation - No Wii software pushing it, and RE5 bundles for the PS3. Its not a normal situation and will likely return to the Wii outselling the PS3 again, especially once the new DQX and MH3 games release. The Wii has been in a software lull for months.
Granted Japan is a weird market. What was a Sony dominated land for 2 generations has seemingly turned a cold shoulder to Sony, favoring Nintendo. Currently, sales show the Wii at approx 2.5 times ahead of Sony. The one other factor that has to be considered is that the 360 is getting some respect in Japan, where last gen, the XBox wasn't a factor much at all in regards to Japanese marketshare. If it were just Nintendo and Sony, it'd be 65-70% marketshare for Nintendo.
The 50% mark is 6mil units. (approx 8 mil for Nintendo, 3 mil for Sony, and 1 mil for XB360 = 12 mil total consoles sold in japan. Thus half -50% would be 6 mil units). Right now, Nintendo is somewhere between 60-70%, (as 9 mil units = 75%). With Sony only making short term gains of 20k units on the Wii, the numbers aren't changing much. As stated before, there's potential on the horizon for the Wii to go back to doubling HD sales combined.
