I'd opt for the fusion concept with a mobile hardware architecture, that could be realized in 3 different forms.
1. A shared architecture for both handleds and home consoles, with different form factors (shared cross-buy libary)
2. An handled console that can be attached to a TV with an HDMI cable or a docking station
3. (That's more imaginative) A modular console with a shorter life cycle that can be attached to different terminals, like a cartridge.
