So... this isn't much use to you at the moment, with no known date for the next update, but...
When you get a ticket that has an Invitation in it, and the Invitation isn't for the brand you want, there's a way to potentially change what the Invitation is. It's convoluted and required a game update - so if your ticket expires before the next update the method isn't of any use.
First you'll want to restore the ticket. You can do this by shutting the game down directly from the XMB without exiting the Gifts screen.
Keep hold of the ticket until the next update, and once the update has been installed you want to open the ticket again.
Note that this may - and only may - change the brand of the Invitation. However it's still better odds than waiting to receive an Invitation to drop from a 4/5-Star ticket only for it to be the wrong one.
