First, as we discovered way back in March, Ikaruga has arrived for PlayStation 4. It's available on the PSN store now. There was some snag getting it on the US store apparently but both Euro and JP stores are OK and to the best of my knowledge the snafu has been fixed in the US store by now.
Quad Fighter K has gotten the review treatment from Bullet Heaven:
Super Destronaut DX, a Space Invaders-esque (that's a real word btw) game, is just weeks away from launching on PS4, Xbox One, Switch and PS Vita.
