'ETX' screen debuting at Tysons!

AMC's version of IMAX - 12 speakers with major ampage, large wall to wall, ceiling to floor screen is expected to open this Friday (March 18th)  at AMC Tysons on their largest screen: auditorium 11.  For some reason I thought the screen that features IMAX (digital) presentations was the largest auditorium, oh well, guess I was wrong.  I will post back my thoughts on the system.
