The answer is actually pretty simple, and mundane. When DVD was announced and the specs settled upon, the whole video industry was aware that everything would be migrating to 16:9 in very short order. Therefore, support for 16:9 (actually, anamorphic 4:3) was built into the DVD spec.
At the time the Blu-ray specs were settled on, there was no plan to migrate to 21:9 on the drawing boards at all. There would have been no displays on the market that could take advantage of anamorphic 16:9 other than anamorphic projection, but the anamorphic market was just not big enough to warrant building in support for the tech.
This is something we will be addressing directly in the next show - our format for encoding 21:9 / 2.40:1, full 1920 x 1080 resolution onto Blu-ray discs that keeps the discs backwards compatible with existing Blu-ray players and 16:9 displays. Now keep this in mind: you will need either a 21:9 display (like the units demoed by Samsung, LG and Toshiba at CES) or an anamorphic lens equipped projection system to take advantage of the higher resolution. Standard HD 16:9 projectors and displays (including projectors using the zoom method) will not be able to take advantage of this greater resolution.
There is one exception to this on the 16:9 side, however. UltraHD / 4K displays and projectors would be able to extract the extra 33% of vertical resolution of of these encoded discs (assuming a correct scaling algorithm built into the display unit, as well as a decoder for our process).
More to come later this week, as anamorphic encoding is only part of the process (Deep Color is the other part).
