Well that's an interesting one, getting in there pretty early.
With MGS5; FFXV and KH3 they are at least on equal footing with any/everything Sony have shown for Japan so far, which is a good thing for them I suppose.
Then again, this generation taught us that even with a price AND games advantage, it still wasn't enough. I wonder if there's any tricks they'll be able to pull out of the hat to change that this time around - I suspect it'll be harder for them to get the exclusive support they had, so it would take something extraordinary.
I also wonder what Sony have to show for Japan. Famitsu was hinting at a PS4-Japan-Event coming before TGS.
