I am very sympathetic with the plight of people who don't have time to analyze the new information provided. Believe me, we did the best we could to make it available earlier - but as you know, it is not possible to announce a deal until the deal has actually been signed. At the last meeting, we knew that this was likely to happen, but we could (of course) not breathe a word about it - it was clear from the traffic on the mailing list and the arguments being fielded in presentations that in the absence of information about the agreement, our assertions about the IPR situation of VP8 would simply not be taken at face value. This was the reason we requested a delay at that time. At this meeting, we believe the important cards are on the table: H.264 is still a royalty-required codec in all its profiles, and has many patent holders insisting on royalties being paid both outside and inside the MPEG-LA patent pool; VP8 is still a codec where all the IPR holders that have made declarations have declared their willingness to license on a royalty free basis (either directly or via Google). We appreciate the need to have time to evaluate the specific words of the license statements that are forthcoming, and the need for the people who haven't made their IPR declarations over the last couple of years of discussion to do so within the next couple of weeks - but we do think that it is important to use the face to face time that we have here in Orlando to lay to rest any *other* issues than the licensing terms and other issues derived from Google's announcement.
