Yes it is John, but is only more powerful if Panasonic supply it to the bike manufacturer without the Japanese legal restriction. Also Leonardo has reported that a Twist rider has fitted the latest twist type unit that's used in the Flyer bike, and that's more powerful with better hill climbing.
I dread to think of the cost though. The replacement of the existing Twist unit is £450 for the part only, and those Biketech prices are usually at least 50% up on ours.
