Although it was a few months later than in Europe and the U.S, the PlayStation4 finally came out in Japan last week. Did anyone get it? 

Tonight, when I dropped by a store on my way home from work, I found that the PS4 was piled up, and some trailers movies was were playing. I almost said aloud, "What a beautiful graphics!" They've just launched it in Japan, so there's there are not many softwares games that I want to play yet. "Ryuu ga gotoku: ishin" looked fun to play. I've never played a game belonging to the genre called "FPS," but watching the movies trailers  for of "Call of Duty: GHOSTS" made me feel like trying it.
I've been longing for the "Kingdom Hearts 3" ever since the "Kingdom Hearts 2" came out, which was already ten years ago. I heard that it was going to would come out for on the PS4 within in 2014, but I don't know if that's true. If that's the case, then maybe I'll buy it.

I must become less serious about my studies if I really get the PS4. :p
Come to think of it, I wonder if you can play softwares games for those successive older PlayStations on the PS4. It'll It will be really inconvenient if you can't.

Once again, your English is very good, I just made it sound a little more natural without changing too much.
