What such an update will look like is not clear. The test program, unlike previous test programs for Dashboard upgrades, involves testers receiving physical items of some kind (in addition to a free copy of Halo: Reach and possibly other goodies.)
An upgrade to the 360 hardware and its disc reading capabilities would be prohibitively expensive (and split the 360 user base) so the "new format" in question probably involves a special kind of DVD, possibly some combination of anti-piracy measures, extra capacity, or a smaller security footprint. Those interested can sign up for the program here.
