Mysterious StreamTV fails to arrive on schedule

A month ago the intriguing StreamTV family first showed up on Amazon promising 500GB HDD, "Super Blu-ray Player" and vaguely worded 3D capabilities. We have now reached their announced release date of May 7 and... nothing. The news of Mitsubishi's 2010 HDTVs with Stream TV (Vudu Apps by another name) seemed like a possible indication of what was to come, but since then we've heard nothing and honestly don't expect to. Anyone out there keeping $5,999 on deck just in case?
