Thanks for the informative articles. I think what has possibly occurred is that Dvico has changed their mind about coming out with the SMP863x series chipsets at this time and for at least awhile, in their media players that is. I, and the rest of us would love to have the ability to stream HD content at 30-50Mbps, but I guess that probably isn't going to happen in the very near future. Based upon the assumption that the company won't be releasing two upgrades within the same year, I am guessing that the model beyond the 4100/5100 won't come out until spring/summer 2008. Obviously I could be wrong, but why would they put the 4100/5100 out now if they are going to be coming out with something almost exactly the same in a few more months? Of course I have also preordered the 4100 and am hoping for some very high transfer speeds, although I seriously doubt that it will get anywhere near the 30Mbps range.
