For Yakuza fans (all two of them):
Yakuza 3-5 remasters are coming to PS4 starting with Yakuza 3 in August

As of now, they've only been confirmed for Japan, but they've brought over the updated versions of 1 and 2, not to mention 6, so I expect 3-5 will come over, too. That'll put the whole 6 games on PS4 in updated form.
