Fernoca, you need to make one adjustment to the info post on the first page.
The Legendary set will remain exclusive to Toys R Us, despite it being discontinued at this time. The others lose their exclusivity.
Toys R Us is actually a parent company to Toys for Bob and Activision. That's how I venture to guess it stays exclusive.
I assume, and I mean ASSUME, the Legendary 2-Pack will come back out, when they release Legendary Trigger Happy. Just a guess. Activision France supposedly told a customer that they are still in production and it may be a month before they hit stores again.
