IMO no leak, just traders/flippers getting positioned for what hopefully will be big news Monday or Tuesday. Volume was not high enough for a leak, and there is no "history" of such leaks (that I know of) with TPL/PTSC.
Someone mentioned the possibility of one or two of the J's settling, with a holdout (Toshiba?) pressing on to trial. IMO that is a distinct possibility, given the apparent difficulty and time involved (30+ days).
Regardless, next week should be interesting. GLTAL.
