Well, you're absolutely right but it's a shame that instead of talking about The G-70 this post as moved to a less interisting issue: the origin of the pic I got from the instrument and wherethere are "leaks" or not. Its enough to begin a new post.
Maybe the information I got is wrong but I still believe it will be a touch screen. Roland released the VAs, one of their firsts touch screen keyboards, and the next synth workstation like the first Fantom (FA-76)had a normal display. So, no reason why this can´t happen again - in color.
