There are some pictures available of the new Terra Plana Neo Trail, which will be released in august. See: http://www.vivobarefoot.com/wordpress/wp-content/uploads/2011/04/SBG-High-Res.png.
This looks like a nice shoe. It has a grippy sole designed for trails but not so agressive as the sole of the Inov-8 Baregrip 200. Maybe this is also a nice shoe for hiking. I own the Merrel Trail Glove which is a very good shoe. But it is designed for wide feet where I have narrow feet. My TP Evo II's fit me much better. So for people with narrow feet the Neo Trail might be worth waiting for.
Downside of the Terra Plana shoes is that they are heavier and have a stiffer sole compared to competitors. Though compared to traditional running shoes they are lightweight and flexibel.
