Probably this lineup will not change the "Japanese market" (I mean: mobile - portable - home console "order"), but I firmly believe that Sony just had a very good and strong Conference. For all their platforms.
PS3: an old hardware, still able to sell software in a positive way. I believe that DQ Heroes could become one of its best selling game next year.
Vita: far away from the nightmarish debut, it's now receive constant support with various games. Probably nothing could be seen as a milion seller or a system seller (tons of sequels, I think) but it should be able to keep its actual pace (that's not incredible but way better than the first 18 months on the market)
PS4: getting a good amount of very important games (Persona, MGSV, One Piece, DQ) from very important IPs. Still multi with other consoles, but (considering how the Xbone is a no-factor in Japan) we could say that even the multi are all "in-house" easing the shifting from PS3/Vita to PS4. I believe that as far as we knoe, we can now foresee a 2015 YTD higher than Wii U for PS4 (unlinke now in terms of weekly pace)
