Hollow Knight, the 2D Dark Souls-like Metroidvania by Team Cherry, has slipped into 2018 for its Switch port.
In a blog post on their website, the developer was candid and simply said that they need more time for code optimization due to the PC version being taped together in an optimized way. The game is up and running, it just needs a bit more work before it is ready for release.
The blog post also mentions that other consoles are being considered. When Hollow Knight was originally announced, the targets were PC and Wii U, with the latter eventually changing to the Switch. Now Team Cherry is in talks with other platform holders, but remains committed to getting the Switch version out first.

Our Take
I have been waiting for the Switch port to play this game after hearing so much lavish praise for the PC version. I am glad they're taking the time to get it right instead of rushing it out to take advantage of the gold rush for indie sales on the Switch right now.
