Those two games could be projects like Mario Kart 7 though where they're assisting another studio. Before E3 I would have agreed with you, but after three and a half years with nothing to show for themselves, I'm really starting to doubt they even have a big project on the go. They've never gone this long without announcing a game before.

We still don't know on what Retro is working and we know that they don't work on any announced game until now, and of course it's safe to assume they are working on their game even if they assist with some other game in same time, also Retros is too big team to be used just like assist team. I think there is nothing to worry about, Switch is just 3-4 monts on market and ofcourse Nintendo did not announced all games that are in development or that will be launched in 2018. If we dont hear anuthing about Retros game in hole 2018. I would be worried, but to be worry now only 3-4 after Switch launch is definitely too early. IMO, most likely Retros game will be released in 2018. Nintendo could easily show game at E3 2018. and release it at end of same year.

They finished Tropical Freeze in late 2013; soon it will be four whole years since then and still no word on what they're working on. They've assisted with other people's games before, like Mario Kart 7, that could be their main role now, plus Nintendo are doing a lot of remasters these days, maybe Retro are just remastering the Metroid Prime Trilogy to get people stoked for Prime 4.

Nothing you wrote go against what I wrote. Point that we still dont know what they working on doesnt mean nothing, like I wrote, Switch is just 3-4 monts on market and ofcourse Nintendo did not announced all games that are in development or that will be launched in 2018. Yes they assisted before with other games (including remasters), but they were making own games in same time. You saying that assisting could be their now main role (despite Retros is big enough to work on two projects in same time or too important studio to be just assist studio), but we dont have any info on what game exactly project they assisting, we know they don't assist on already announced games, so they posible assisted game or posible their game are still not anancued, in other words you don't have nothing to backup thinking they just assisting or working on remaster.

If we dont hear anuthing about Retros game in hole 2018. I would be worried, but to be worry now only 3-4 after Switch launch is definitely too early. IMO, most likely Retros game will be released in 2018. Nintendo could easily show game at E3 2018. and release it at end of same year.

3.5 years is not too early to be worried. Given when they started, their game should have been a launch title.

No its not, like wrote Switch is just launched, Switch has very strong launch with Zelda BotW and there wasn't need for another big game. We dont know how big their game is, this year is already very strong for Switch lineup, Nintendo could easily saving Retros game for next year even if its almost done, and we already know Nintendo like to have smaller amount of time between announcement and launch. Also, those 3.5 years goes in both ways, for possible assisting/remaster or their own game, fact we still dont know what they are working doesnt mean they assisting/remastering, and there is no reason to assume they don't work on own game and that they are just assisting/remastering when evre time before they were assisting/remastering game and working on own game.

Worst case scenario that I think is that they Wii U project is totally cancelled and they started working almost from start on Switch game, but most likely scenario that their game will be released in 2018. Retros game could easily biggest new Switch announcement at E3 2018. and I am sure we will at least see their game in sometime in 2018. latest.

By the time Switch came out they'd already had more than 3 years to work on it. It could've taken the place of another 2017 title. But now that E3 2017 has come and gone with no word despite Kirby and Yoshi being shown, it's a distinct possibility that they simply don't have anything to show.

Like I wrote, we dont know how big their game is, this year is already very strong for Switch lineup, Nintendo could easily saving Retros game for next year even if its almost done, Nintendo even basically said that Mario Odyssey could be dont for Switch launch but they decided to be holiday season because Zelda BotW alone is very strong game. Like you wrote, DKTF was finished at end of 2013. so of course they working on same game/games from that time until now (it hard to imagine they didnt do nothing at all), only we dont know on what game/s that are working. Yoshi and Kirby are smaller games and they look like there will be released in 1st half of 2018. Retros game is probably much bigger and stronger game, so probably holiday 2018. game. Like I wrote, Retros game could easily be biggest new Switch announcement at E3 2018. and I am sure we will at least see their game in sometime in 2018. latest. My best guess is that Retros have two projects, one own and one co-developed, and I epxting that at least one will be released in 2018.

If they're saving it for next year then it would be far enough along to show it, and when you're trying to make your system's future look bright at an event like E3, it makes more sense to show a big game from one of your flagship studios than second tier stuff like Kirby and Yoshi. Unless of course, Retro's game is itself a second tier game. Their games have been getting less ambitious for a long time now.
