$2700 is just too much for me for a field monitor. I'm happy with my Zacuto EVF Pro.
I've mentioned them about the 2x squeeze a few months ago they asked for more info and I sent them. They replied it might be included in the new version of their EVF.
I think cheaper monitor like Lilliput might have these options soon. I've emailed them sometimes ago. They seemed to be interested in the feature as well since it requires only some firmware tweaks. Maybe, if we have enought voices they might add it sooner :)
