I'm interested in a compelling/competitive 3rd console to compete with Playstation and Nintendo and I agree Capcom has great IP, I just don't know how it would work. They'd just stop releasing their games on Playstation, Nintendo and Xbox consoles so you buy their consoles to play their games (I would do this)? I don't know if they'd do that though. What if their console doesn't sell well? They just scrap the console and go back to being a 3rd party dev?
The lack of enthusiasm for Xbox with their multi-console and PC approach to releasing their 1st party titles makes me question how Capcom could succeed as a console manufacturer if they kept releasing their games for the other consoles.
I respect Capcom and their IP and if it could work I'd be interested, I just am not sure how it would work. Capcom vs SNK 3, a AAA Mega Man, Street Fighter 7, etc, etc all exclusive to a Capcom console. There would be hype, I just think the risk and likelihood of it being a Dreamcast experience (a beloved console but not commercially successful) and ruining relationships with Nintendo and Sony is too high.
