Backward compatibility is probably huge, especially when you see the amount of software the PS2 is still moving in Japan........
Sony needs to release the 80Gb in Japan ASAP and as part of their certification process make sure every new PS2 game works on it ( because there still are a lot of new PS2 games coming out in Japan it seems).
And yes they probably need to drop prices in Japan ( dropping the price there only woudn't be such a huge financial hit because they are never going to move 100k units/week there anyway).
They need to get games that will work well both in Japan and the Western World too. If you check the best sellers on PS3 in Japan right now, most of them are titles that do only well in Japan ( aside DMC4 and GT5P) and it's not possible to recoup costs of huge games with just the Japanese market this generation..
Look at the Wii best selling titles in Japan, almost all of them sold as well if not better in NA or Other...
MGS4 and FF are such games but they need a lot more than that.
PS3-Xbox360 gap : 1.5 millions and going up in PS3 favor !
PS3-Wii gap : 20 millions and going down !
