It looks like the 4th volume of the Friendship is Magic Australian box set has finally popped up for pre-order. The release date is listing October 3rd, so we have a bit of time before it officially releases.
Sadly all the pages aside from "add to cart" 404. I guess we have to wait until it completely updates!
And just a heads up, this is actually region 4 only. If your DVD player doesn't support Region 4... import an Australian one! You know it's worth it!
