I would have to be convinced that the "partner" you allude too is not distinct from the "sponsor". FB has been in the VR driver's seat from the $2 Billion & Palmer Luckey. A "sponsorship" on the 4k display would not preclude others from others getting in on the act but speed VR integration. Interstate Battery sponsors Joe Gibbs Racing but Joey Lagano drives the car with a whole bunch of others stickers on it Craftsman Tools, M&Ms, FedEx. Look at the content blitz FB is on. Assassin's Creed, Splinter Cell. Oculus Hub, Facebook, The $$$ will be in content, They may want to be first and the development money is chump change. Oh yeah and these guys have mastered "shadow talk."
