I've seen on some schematics of the xnodes and how theyll function (big picture style) and what the eventual upgrades will provide. There have been some technical discussions, code was reviewed via teamviewer and confirmed it was different that what the rumors had speculated (original code in other words and not a copy of something else). Hopefully though, what I'd like is an official whitepaper explaining everything on a technical level, which is something that is apparently in the works. Scepticism is good for any new coin, especially those making big claims, what I do know is that the releases have come as promised, tonight release went well, and the fork was corrected with impressive speed by pushing out another wallet update while coordinating with the exchanges etc (was on the freenode, to see it in action). As with all things in crypto, time will tell what happens in the next few weeks/mths. Could be a told you so scenario or devs could certainly come through and silence the critics.
