An e-mail I received... just posted for interest:
We are super excited to announce a new addition to the IOT Developer Program – Raspberry Pi 2!
In partnership with the Raspberry Pi Foundation, we are going to make Windows 10 available for the Raspberry Pi 2. You’ll be among the first to know when we make Windows 10 available for the Raspberry Pi 2.
We will also continue to support the Intel Galileo through the program.
By being part of the Windows Developer Program for IoT you continue to be amongst the first to receive new information about the program, product announcements, beta program updates and launch specifics.
