2010 is too early, imo, for a new console. While logistics prevail that Wii HD could be done, it isn't common practice for Nintendo. I'd expect a 2011 release of Nintendo's next home console. After all, 2012 is 6 years from the release of the Wii. The GC came out in 2001 in the US, with the Wii 5 years later. The N64 came out in 1996 in the US, and the GC came out 5 years later. The SNES was released in 1991, and the N64 came out 5 years later. The NES came out in the US in 1985, and the SNES came out 6 years later.
What I'm saying is, Nintendo seems to be pretty consistent with a 5 year life cycle, with a max of a 6 year cycle. Since the Wii came out in 2006, 2011 would fit the pattern properly, with a max stretch to 2012.
I wouldn't be shocked to hear about Nintendo's next system at E3 2010, but we won't be getting an "HD enhancement" as Pachter seems to think.
