There's already a lot of Allwinner-based Pi clones with no magical binary blobs, though - depending on the board the only blob may be the non-modifiable boot ROM, which is actually quite convenient for low-level hackers since it just loads your own bootloader from one of several devices and gets out of its way. This includes support for raw NAND flash so in theory you can avoid even having a binary blob in your storage device if you get one of the few boards with raw NAND onboard.
