the only financial plan i've heard of is the 25/75% split btwn the consumer and 21, so the consumer is going to get spending coin.
I'm pretty sure in the white paper-ish thing they posted it says that the split can be anything, and is up to the manufacturer of the devices. I don't remember if it explicitly said that 21 will be using 75/25 for any particular devices or if that was just an example, or earlier speculation from third parties.
