Two points,
1) The initial news outlet was incorrect about the shipment to Verizon, later reports have corrected this by stating HTC shipments to Google for the Verizon compatible phone.
2) I see no reason why Verizon would carry it in stores, unless they arranged for a demo/display model with Google. For training or marketing, whatever. The phone will be sold online just like Tmob and now Att. If there is a decent argument the other way, i'd like to hear it. Up until now, I've just heard wishful nonsense.
