Really? How would we know when the second shipment would be arriving... shipments are arriving left and right at corporate stores and other retail outlets.
I would say that newer batches would begin shipping once current stock is depleted. Once again, no time frame.
Also, nobody is promising these "issues" to be fixed in their next production run. It may take some user feedback and time until these are addressed.
I would say buy the TB now. I have not had issues with pink tint or light leak. People are extremely sensitive and picky. If you do have a real problem then Verizon will swap out with another TB... no questions asked.
