Bonus content with Nexus 4?

I got my Nexus 4 yesterday, and now I see a ton of new "purchases" through Wallet that I have no idea where they came from.

So I went looking through the various content apps to see if they were indeed available to me, which they are.

Did I miss this as part of a promo or something?

(this is about 20 items total, a little bit of everything, TV Shows, Movies, Books, Magazines & Music)
