Yes, I agree. All power meters seem to come with a compromise hardware-wise (pedals being the most versatile.) Just checked the Brim Brothers facebook page and they claim their first units have finished production, but who knows when they'll ship, plus they'll probably go to early backers first. Then there is the question of whether it actually works... Fwiw Luck recently announced power meter soles for their shoes at Eurobike, which is another interesting approach but again, until I see them actually being sold I wouldn't hold my breath.
