The main problem with WebM/VP8 vs. H.264, especially in the face of the mobile internet device explosion, is hardware acceleration. Once devices start coming with native WebM acceleration, it won't be an issue. Given that Android is so popular and Google is looking to abandon H.264, it's inevitable that hardware acceleration will come to phones, probably in conjunction with H.264 acceleration (just like H.264 and H.263 right now) At that point, any ARM platform with a H.264 acceleration will include a WebM acceleration, and it would be more than trivial for Apple/Microsoft/whoever to implement WebM in their mobile browsers. A more interesting day will be when Google says "Android 3.x phones must have WebM acceleration"
