Honestly if Nintendo released a higher end Wii 2 and for the first year maybe just kept developing Wii games but offered HD versions of Mario Galaxy 2 and Metroid Prime Other M and Zelda on Wii 2 in 1080p + Dolby Digital + a more streamlined Wiimote ... I'd be quite fine with that.
They can ramp up "built only for HD" titles later on, but you'd have third party stuff like FF13 and RE5 and Dead Rising 2 to go with those first party games in the meantime.
Maybe it is time for the traditional idea of how one console phases out another to be thrown out because quite frankly it's an outdated method really based on the days of the 80s/early 90s, where most main consumers of game systems were kids who had to get permission from their parents to buy a new machine and parents weren't about to plop down cash more than 5 years at a a time.
Maybe its time for an idea like "forward compatibility" to be really tried out.
