If that's the time line then Golden Week for Japan would pretty much be a lock, Nintendo almost always tries to get a big game in during that period for Japan. So late April/Early May? 

Well .. I knew Animal Crossing would come to Switch in 2018. But now it's looking officially early-mid 2018, possibly May, maybe April or June?

I kind of expected that though.

Of all the franchises AC is the one that fits mobile with little change to the core experience which is a given I can see them doing a Tomodachi app in future as well.

It's already out in Australia. Playing as we speak

Was gonna post this lol, just done downloading the update.

i like it. It's like happy home designer. Definitely see myself playing it on the bus to work

lucky you.  apple folks are having difficulty switching regions now it seem impossible since the ios updates.

Only played New Leaf, put in about 70+ hours until my daughter unknowingly deleted my save file, sigh that was a sad day, never played it again, hope they announce a switch version already, but until then, this mobile version may suffice for now.

The game looks really good. Like Fire Emblem Heroes, a very interesting use of the license that stays true to the franchise, markets it to a wide audience, and will ultimately get Nintendo's presence more well known to new potential fans.
