You're essentially describing a console: a system with fixed hardware requirements that will last for several years. That's the ultimate advantage of being a console dev - you have no variation in hardware whatsoever* and if your game works in the studio, you can be 99% sure it will work on any identical console in the field. And generally throughout the lifespan of the hardware, the games get progressively more advanced as the developers learn how to fiddle the hardware to do what they want.] *not totally true, but ignoring things like disc space and peripheral availability (like the SNES coprocessors - even then they were in-cart!) all consoles can be considered equal.
