I ordered one "just in case before they run out" 
. I'm just in the progress of moving Node-RED & various related home automation services from an Odroid C2 to a 4GB model. I thought why not have 8GB there already as I'm planning on running it the next 2+ years like previously with the Odroid.
The 4GB model can become the brains of cottage automation and the originally planned 2GB model can be used as a beefy Pi camera.
