Canon upgraded one of its higher-end home camcorders today in the form of the Vixia HF M32. The design closely follows that of the M31 but doubles the built-in flash to 64GB and upgrades the card slot to support SDXC. With a lower bitrate, Canon believes the camera could hold a full day of video in built-in memory alone and another day again with a 64GB SDXC card.
