FUD. You think H.264 decoding is done at the gate level on your chips ? These are programmable ASICs you're talking about. The H.264 decoding is actual a software program that runs on top of it. This can be updated to do VP8 and you will get the benefits by updating the software on the device, not by changing the device completely.
Your posts are usually bullying and either (clueless|dishonest), and this is no exception. Yes, everyone is going to open up their device and flash the ASIC. Or, maybe device manufacturers are going to issue a firmware update that will (where it's possible, which won't be every device) enable and perform such a flash?
Get real. I am relatively sure that such a thing has never happened. It's a ridiculous claim of "possibility".
