April afaik, but im not sure where I got that from...it will be soon enough anyway, cant be any later than may or june, from what i remember last year.
Ishibashi has a few 8270s and 8170 discounted by a small bit, including a black one if i remember rightly, suggesting the new ones will be in soon. When the 2006 models are released, you'll pick up a 2005 model at a good price..
i doubt the new ones will be a return to the old spec (
maple fingerboard binding etc.) so if you really have to get a new one, best to just keep an eye out for a cheap 2005 model.
