The new Bikeradar.com site (formerly cycling.co.uk) gives a first look at Look's new 586 high modulus carbon road frame that will come out in 2008.
It is 100g lighter than the frame it replaces. Like it's predecessor, it has an integrated seatpost, but this model includes elastomer blocks in the post that will help to soften the ride a little bit.
The same article mentions the introduction of the Keo Grip cleat. Apparently this is the Keo cleat with some rubber grip pads to help keep your feet under you when walking.
The new products can be seen at Look Cycle's web site.
As an aside, I see that the review was written by Gary Boulanger, of the late, great Cycles Gaansari.
