German Heise reports that JVC showed an unreleased JVC Everio HDD camcorder with full HD video resolution recording behind closed doors at the IFA 2006.

The new Everio camcorder would hit stores in 2007 and does not have a model number yet. Besides the information that this new Everio will record 1,920 x 1,080px video with 50/60hz frequency nothing has been revealed by JVC. The photo (by Heise) apparently shows this new HD Everio.
The latest compact Sony HDD camcorder only record 1080i HD so far. I am pretty sure Sony will update its line with full HD camcorders as well in 2007.
The current flagship JVC Everio is the JVC Everio GZ-MG505. Find deals for the GZ-MG505.
