Here's another group of Wii U and 3DS eShop games that were delayed but are totally coming soon.
Scram Kitty and His Buddy on Rails

Developer: Dakko Dakko
Platform: Wii U
Previous Release Window: March
Current Release Window: Very Soon
What is it?: The name is a dead giveaway that Scram Kitty and His Buddy on Rails is a weird one. It’s a quirky mixture of shoot-’em-up and platformer with rail-based movement. And like, you control a friend of Scramy Kitty who has to fight mice and mechs in a space station. Or something. It’s weird. Check out our preview for more details.
What is the developer saying?: We didn’t get a reply from Dakko Dakko, but the company did recently tweet out saying that Scram Kitty is just waiting for a release date at this point.
Squids Odyssey

Developer: The Game Bakers
Platform: Wii U/3DS
Previous Release Window: March
Current Release Window: Nothing definite
What is it?: Squids Odyssey is an action RPG where you build up an army of class-based squids to fight in turn-based battles against other evil sea creatures.
What is the developer saying?: “The basic answer is that Squids Odyssey is still going through the submission process and we don't have a definite release date yet.” Emily Morganti, PR
Monkey Pirates

Developer: Henchmen Studio
Platform: Wii U
Previous Release Window: Q1
Current Release Window: May/June
What is it?: Monkey Pirates is a novel attempt at rekindling old-fashioned local multiplayer. It’s not about mini-games; it’s about naval warfare with friends. Check out our preview for more details.
What is the developer saying?: “It is the good old reason, but still very true, of the time needed to have a better experience for the player. We were good to go by the date we announced (April 3) , but we still had some framedrops in the game so we took the decision to delay the game in order to get rid of them and have a nice fluid and polished game. But today we are ready for our final submission, which mean we should be out in a month from now. We’ll communicate as soon as we have a fixed release date.” Christophe Siccardi, Henchmen Studio
