Even though the Titan/Mogul is limited in hardware and inevitably only so much can be squeezed out of it, the next model in the 6600/6700/6800 lineup (I presume the 6900) will be even better. I believe HTC has felt the influencial impact that forums such as PPCGeeks & XDA offer and have heard the battlefield crys; the result which hopefully will include public beta testing, delivered-as-promised upgrades/revisions and increased hardware capacity.
You didn't happen to snap any photos while you were there did you? Did you see any future demo units?
