I don't get why do you think everyone will go to Undertale Wiki for Deltarune information. There have only been a few users adding (and attempting to add) Deltarune information to Undertale Wiki, which tells me they are instead going to the Deltarune Wiki and adding it there, and the flow of editors is probably comparable to the flow of viewers. I don't have any real statistics either, but as the new wiki is rapidly being expanded at the moment there is no point in moving its content here at this time.

When the activity dies down a little, we will consider starting a community vote about whether the other wiki should be merged into this wiki and about the specifics of the merge. Until then, we will be linking to the new wiki for Deltarune-specific information.

Considering the Deltarune FAQ, it is also debatable whether it's the "same series."
