The 3DS version is slated to launch in Japan in July IIRC, so this will definitely be a hype direct to get people excited for the 3DS version. Discussing the Switch version risks undermining the 3DS version sales, and it would be in SE's best interest to not mention it at all, or to only bring it up right at the beginning or right at the end, maintaining focus on the guaranteed incoming release.
I'm still not all that certain what they'll choose to do for the Switch version, and I imagine right now they're evaluating if the concessions they'll have to make to meet both docked and portable requirements will compromise their vision of the game. Just because some of you are okay with a graphically gimped version of the PS4 game doesn't mean SE will necessarily want to pursue it if they feel the version will be too vastly inferior to the PS4 version. Remember, they have to keep a proper sales outlook in mind, and considering the Switch version is guaranteed to come after the 3DS and PS4 release, they'll have to find some way to reasonably market it after it has already sold PS4s and 3DSs.
