Take it with a grain of salt, but according to Wedbush Morgan analyst Michael Pachter a HD version of the Nintendo Wii console may arrive in 2010. Furthermore, Pachter expects other next-generation consoles won't arrive before 2013.
"We do not expect the 'next' generation to begin before 2013, if at all," said Pachter in a newsletter today.
Specifically, Pachter said to not expect any new hardware in 2010 other than "the long-rumoured high definition Wii, which is likely to upgrade the Wii to current console technology."
