Nintendo hardware has a number of exclusive sonic games /because/ they perform better there, not the other way around. If it were financially sound to have exclusives on the other platforms, they would have had them too.
This thinking didn't do the sales for games like Lost World or Boom any favors. Both the 3DS and WiiU SKUs for Lost World combined barely crawled past 700k. Boom couldn't even crack half a million. It's clear they need to move beyond relying on Nintendo consoles for the bulk of their sales, since it's not guaranteed anymore.
I mean... Your definition of high end platformer is some PS1 remakes which released at a budget pricepoint and had three games of old content included? Uh...
(Ratchet PS4 doesn't seem to have solid sales numbers, but it isn't even anywhere close to crash or spyro)
To clarify, I meant lower budget development, not necessarily budget MSRP. Crash and Spyro may be remakes of PS1 titles, but they at least looked beautiful and like they belonged on current gen hardware.
Ratchet PS4 was the most successful Ratchet/Insomniac title in their entire history (until Spiderman of course). And also looked amazing.
You put in a real effort, the fans will come.
Forces had such a low budget, so much outsourcing, and loss in key staff, it ended up looking
worse than Unleashed, a 12 year old game. Hell, it almost looked worse than Colors!
Not a single company would ever consider doing this at this point. Game development became so much more expensive since the Wii and Ds/3ds hardware left the market with no options for budget development. Making an entirely separate game for current gen level hardware when sonic team are evidently stretched thin trying to make one game is likely impossible.
By asking for a high end next gen game you are by default asking for there to be no switch version and no third party making a game like sonic is going to make that decision.
This is ultimately Sega's call, but with the success of the Sonic film, they may feel more comfortable in expanding the budget to cater to two consoles for the franchise's 30th anniversary. Again, this wouldn't be new territory for them having done the same with Unleashed, Generations and Lost World.
