Absolutely agree! In this case, the game you want also happens to be a game I think Nintendo needs. Not needs as in, "OMG it will save the Wii U/revitalize the 3ds!!" but just that it will strengthen an already diverse library and see the resurgence of an undervalued series. Unfortunately, Camelot is too busy making stuff like Mario Tennis to bother with niche titles like GS right now. I can't blame them, either. Wii U especially, needs revenue and Mario will bring in more revenue than Golden Sun.
I've only played the first GS, but it was an amazing game. Like you said, having a holy trinity of JRPGS would be a great pillar for Nintendo. It'd be amazing for Wii U (or 3DS) but I think they're going to play it safe until this gen is over. Hopefully, we'll see it land on NX?
Also, I do think Nintendo needs Metroid and F-zero more than Golden Sun since nothing else like either of them them exists and we already have a few JRPGS on Wii U and 3ds.
It'll be awhile before I figure out how to do one of these. :P
