Look at the PS3 in Japan, yes it's not so good now, but it has potential to grow it's userbase and compete competitively with the Wii even if it does take a long ass time to get there. It's only 3 million short of Wii's total, while the 360 is nearly 4.5 million short.
The PSP proved that it can bounce back and Sony obviously realized that the trick was to re-design it's portable system to bring in customers. I'm pretty sure they know how to bring back the love for Playstation to japanese consumers as well.
Whereas Microsoft just doesn't understand that nobody in Japan wants a 360 because they hated the first one and online gaming is not a selling point to them. Those JPRG's, and let's conclude Microsoft has like 5 out for it in Japan compared to 2 of PS3's and yet it still can't sell at least 10k a week.
Thus the PS3 has potential to grow and if the japanese dev's would stop believing in Microsoft to taking over the world, their jrpg series won't have to suffer anymore because of it.
Look at Europe, with a year head start, the PS3 has managed to sell almost equivalent to the 360 and it is outselling it finally both hardware and software. the PS3 games there actually have legs to boot. Thus, it has potential to expand there now which it is doing.
As for the U.S, despite it still being a huge disadvantage and being behind, the PS3 in sales are coming in close to the 360, and with the bad economy, only a cheaper price can fix that along with their big titles like LBP coming out this fall. Now that Microsoft is trying to court third parties with no more good first party titles, they are gonna use their money like crazy to buy out exclusives.
Microsoft had their chance to be the next "PS2" but let's face it, its potential to grow has faded and soon America will buy into it again as well. I think Sony was smart not to buy that GTA4 exclusive $50 million DLC cause it didn't sell consoles at all lol.
