Let's just hope they never even consider a 3DS port. There is literally no way Armature could downport that.
As for Vita, I will be happy to play it on it eventually, even if there is no way it would not affect things. To quote just a very small portion of my post from the 143rd page that was clearly too big for its own good:
This of course is exemplified by the Vita port, so we can absolutely not expect this game to match up to a PS4/XBOX ONE/PC native project, but the truth is that it probably never would have. What matters more is its gameplay, which is less likely to be compromised by all these ports. Honestly, if the game looks like a mid to high end Wii U game (see Nintendo's frst party output, Bayonetta 2, etc.) and is appropriately scaled on the other platforms (1080p/60 on PS4/XBOX ONE, whatever you want on PC, and 30fps and probably some acceptable sub-native resolution on Vita) I'd be very happy. What matters for aesthetics most is its artistic quality, which will probably be well expressed regardless of tekch. The game was always going to be heavily based on SotN in terms of the scope of the gameplay, so sprawling areas that wouldn't fit in the Vita's RAM were probably unlikely to begin with.
