I just checked TigerDirect.ca again and it now says "Available While Supplies Last". The explanatory popup says this means they have a limited quantity and once sold out may not get more.

Glass Half Full: There's an imminent hardware refresh and they want to clear out existing inventory (always a good thing for a company to do).
Glass Half Empty: TigerDirect.ca will no longer be carrying the PE (not a good thing )

Rest assured enTourage will not be telling us anything about the situation
