I personally don't think they will, or will wait a long time to do so. They just got MV in the United States. It depends on the success of MV, and I don't think it was that successful that they would move onto MZ so quickly...
Would be nice to deploy games to Switch though, like Pixel Maker!
Oh, I don't think it'll be done quickly and agree with that, but I'm wondering if people think it will be done.... let's say as long as a few years from now. I guess MV is still new on Switch like you said so maybe this is too early to guess.
I honestly think at least 5 years for another console release at minimum. I think RPGMaker as a company needs to redouble the marketing efforts and such, there is a lot of competition on the horizon. I think a new branding would be prudent, and more universal asset sizes, or more options, will keep it competitive.
Frankly, I hope not. I have no clue how anyone ever had patience for console RPG Makers, especially without keyboard support. This goes double for a lack of good game distribution and importing assets. It seems more like a toy than even a hobbyist's game dev software.
Given the timing of RPG Maker MV console versions (released near the same time as RPG Maker MZ), I wouldn't be surprised if this was a way to get new RPG Maker users on consoles interested in the engine and then move to MZ on the PC. It makes sense to buy the latest version if you already own the previous one. New users will feel like it's a huge upgrade due to how restricted the console versions are. For that reason, I predict that we won't see another console version until a new PC version gets released.
Judging on how limited space you can make a game on said console, I rather think they won't be another one consider like most RPG makers for consoles, they bound with limitations because on how the console power compare to PC because of this they might reason why space is tight in a console and the little things can do
