I heard that, too, but....
Saw BPS/Cabela's had their spring fishing catalog out so was checking it out. Took me to this site:

They say that graph has the Livesight but I didn't see ANYTHING in their videos that looked like the Garmin Panoptix.
I guess, further down in the description it just says it is "compatible"....does that mean it is upgradeable once it comes out?
