I love my Variax 705 bass and it's very clear that Line 6 are done with the Variax 700 & 705 models and probably any future bass models. Don't expect any s/w updates including Workbench ever being developed for the basses cause that's just never going to happen. They realized a number of years ago that there's just no return on the investment that would be needed to develop it which is really too bad.
That being said, I just continue to use my 705 as a work horse and enjoy it.
