Garmin Oregon 500 series with built-in camera leaks out

Looks like the latest Garmin Oregon nav unit is following in family footsteps by leaking out a little early -- listings for an Oregon 500 and Oregon 500t appear in the latest REI catalog. The pair are basically the same as the Oregon 400 / 400t, with the addition of a built-in digital camera that'll enable you to take instantly-geotagged features. Definitely a neat idea, but convenience won't come cheap: the 500 lists for $549, and the 500t is $599. No hints at a release date, but we'd guess it's coming soon.
