I enjoy only a couple Davidoffs, including, the Millenium lancero and robusto and maybe an occassional (FREE!) regular line petit corona. I will say, having just gone to a Davidoff event a few weeks back, that the new Millenium blend double robusto is quite good. It's a much darker, richer, more full bodied smoke than other Davidoffs. I actually enjoyed it.
The limited release, I heard, was coming out in full production in January. I believe this came from the rep at the event. Other than that, I haven't really heard anything about those.
