Deal is now live in US store. D3 and RoS at $20 each.Battle.net Taiwan has D3, D3: RoS for NT$575 each. (approx. 18.88 USD)
Players can play in any game region with this but I'm not very sure of how to successfully purchase it (with an existing SEA Bnet account for example). Its a good price but try at your own risk after a little bit of research.
