My predictions:
EAD 1: nothing, maybe Mario Kart 8 DLC
EAD 2: Animal Crossing Wii U (2015)
EAD 3: Legend of Zelda Wii U (2015), Majoras Mask 3D (Grezzo- 2014)
EAD 4: 2.5D Metroid (2015)- I say this as the producer of EAD 4 (Hiroyuki Kimura) has made 2D Metroid titles in the past. As this team makes the 2.5D Mario games (and those games have already been released on both 3DS and Wii U) maybe this group will develop the next Metroid with Yoshio Sakamoto as an advisor.
EAD 5: This could be the group working on the fabled new Miyamoto IP. This group appears to be small as they outsource their games (Wii Fit U- Ganbarion, Starfox 3d- Q Games, Steel Diver- Vitei), and Miaymoto expressed interest in working with a small group of relatively inexperienced developers.
EAD Tokyo 1: Have not developed a major release since Mario Galaxy in 2007. I would imagine they are working on something. The producer of this group (Takao Shimizu) was the director of the Pokemon Coliseum games. Could he be making Pokken with Namco?
EAD Tokyo 2: confirmed to be working on a new Mario game but probably too early to show.
SPD 1: This group is always a wild card. I have no idea. Something wacky, but interesting.
SPD 2: Intelligent Systems- SMT X Fire Emblem, Paper Mario Wii U (2015), 3DS Wars, Monolith Soft- X, Hal- Kirby (Wii U- may be early and not ready to show), Platinum- Bayonetta 2, Good Feel- Yarn Yoshi (2015), Sora- Super Smash Bros, Ndcube- Mario Party (2015), Valhalla- Devils Third (speculation)
SPD 3: NST- the recently trademarked S.T.E.A.M.?, Retro- probably too early to show whatever it is they are making, Next Level Games- LM 2 was ready in 2012 so they could have something ready by early-mid 2015, Monster Games- recently completed DK:TF with Retro and they are small so maybe nothing from them yet, Headstrong Games- Battalion Wars (2015).
