This site is devoted to change that version number into 3, hence the name DVI3. The main goal is to make DVI3 just as platform independant as Portable Document Format. The good things of DVI2 will stay, the bad things will be left behind, and many new things will be added. Though this has not much meaning for the average TeX user, the printing industry is waiting for good, decent color support. There is a good model for colors, which is actually usable.
Fonts are a nuisance in TeX, and especially in the DVI format.
There is currently no support planned for OpenType fonts. These are all well known standards with well known libraries for rendering. Vector graphics support. The actual scripting language is currently not known but it will probably be Javascript, java, Guile, or maybe even perl. Wouldn't it be nice if you could actually create a program from within TeX, that has stunning graphics and amazing user-interaction.
