So SE repeatingly confirmed DQXI for the NX/Switch, and said it will have its own version different from the PS4 and 3DS versions. Will it use UE4 and just have a few concessions, will they just upgrade a poet of the 3DS game, or will they do both? What do you think?

Probably closer to the PS4. The Switch will be closer in power to the PS4 than to the 3DS.

Same as the Ps4 version with half the resolution maybe.

It'll probably be more similar to the ps4 version, albeit at possibly a lower resolution and maybe at a lower framerate, depending upon factors like: how taxing is the game itself on hardware, and what the switch's actual specs might be. 

It'd have to be more like the PS4 ver than the 3DS one

Hopefully it will be PS4 port rather than 3DS port, graphic downgrade a little bit would be acceptable to me.

A slightly downgraded version of the ps4 title.

Hopefully it's close to the PS4 version as possible.

I could imagine that it just gets both versions you can switch between. There is really no reason not to include both versions in home consoles anyway.

720p, still no idea how that can be close to the PS4 version. Tegra has no grunt, probably look like a PS3 720p title imo.
