Minecraft PE vs Windows 10 PC Beta

[Legoboyii]

If i buy the pocket edition which will therefore make me an existing user upon registering i can get the windows 10 beta free?
Can pocket edition be installed and played from a Class 10+ sd card?

Sorry, found out the free access only includes existing PC/Mac users only. When is Minecraft Win10 hitting mobile as well? Dont want to buy PE if its going to be a waste of money in the near future.
