Wii will, Wii will drop U.
A notable update was recently released for Wii U eShop title Blok Drop U.
If you haven't downloaded the update already, it will automatically download when the title is launched.
Developer RCMADIAX added sound effects and save states, improved graphics, among other things to improve the puzzler.
Looks like the update for #BLOKDROPU should now download automatically when you launch the title.
