These are the titles (with confirmed release date) that I think will boost PS3 sales in the first half of 2008 in Japan: Devil May Cry 4, Disgaea 3, Yakuza: Kenzan, Valkyrie of the Battlefield: Gallian Chronicles, Metal Gear Solid 4. I believe that Japanese gamers will eventually embrace PS3. Why would they want to get a PS3 now? Most of the good games they want are for PS2 and PS3 games on the market are mostly western titles.
Japanese game developers are very anal with the quality control. Give them more time and they will start releasing games in a much faster pace (like PS2). It's not a big deal that PS3 has a slow start in Japan. In fact, the consequence is that more Asian gamers can get the opportunity to experience more western titles. It is actually a good thing for the gaming industry.
PS3 may be in a tough position in Japan and NA now, but it doesn't mean that is the end of it. A lot of people are waiting on the side line to jump in when it becomes cheaper/slimmer. The playstation brand is simply too big to be ignored. Besides, Sony is better off by making more money from "the others" regions because US dollar and Japanese yen doesn't worth as much as "the other" currencies now 
It (PS3's market share) might hit 30%, but definently not more. ~ Neo
