If that's the only tv-out it's pretty lame... Considering the device can capture in 720p but can't output in 720p!* There's a slim chance MHL is implemented via mUSB, hence enabling HDMI signalling & 720p-out. It's unlikely as it's not explicitly mentioned anywhere... But i hope-to-god it's just a few step away from do-able, with the right driver/fw etc. *then again this may be the case, simply because the SoC can't handle true (not rescaled) 720p output?
