I'd need to see the system, but the broader issue is does the mass market, as in the "normal" consumers and not Nintendo die-hards even want a Nintendo console?
Just because you improve some things doesn't mean you will have better sales either, that's one thing I don't think a lot of people get.
The GameCube improved on the N64 in several major areas ... it dumped cartridges for cheaper optical discs, was easy to program for, they even got a massive commitment from Capcom for Resident Evil exclusivity and several other games.
Yet GameCube still sold worse than the N64.
Dreamcast was a huuuuuuuuuge improvement over the Saturn, it had a real Sonic game, Soul Calibur at launch, NFL2K, pretty strong third party support, great Sega titles ... it still sold about the same as the abysmal Saturn.
