They. Do. Not. Know.
Would you prefer they pulled a date out of their arse and just lied to you?

We just have to be patient and will be provided with as much info as they have when they are given it by the brands/suppliers.
I can only imagine how frustrating a time this must be for any tech store staff to be stuck in the middle of this mess.
They. Should. Push. Suppliers. Harder. For. Info.
