Those new ponies are actually already up for sale. Check out My Little Pony Mini PVC Sets New!

They're selling them in sets of three, I believe they're blindbag sized, though I could be wrong. The three sets are the Apple Family, Cloudsdale, and Canterlot wedding; Big Mac, Granny and Applejack, RD Gilda and Spitfire, and Shining Armor, Cadence, and Twilight respectively. It's a bit of a markup from hunting the blindbags down individually, but I don't think Granny Smith, Gilda, Spitfire, Cadence or Shining Armor have popped up in any of the blindbag waves yet.

To answer your question, yes. I am absolutely ashamed of the amount of time I spend watching for MLP releases. It's a necessity, my wife doesn't have a Lyra to take out of the box yet. (We try to snag two of anything we get, I keep my stuff Mint-in-Box, she takes hers out and displays them.) For anyone that manages to comes across one anywhere, I have several extra toys for various reasons, including a couple rather rare Trixies, in the box. I will trade for a Lyra, and love you for it.
