Don't know too much about the Roland arrangers...Is the E-80 the newest?

How does the E-80 compare to the G-70?
Besides the 76 vs 61 keys.

I see Sweetwater has then both in stock...I may go there to check them both out this week???

I assume V3 of the G-70 is just a download and install on any G-70?

Thanks,
Lee
