Lost Seasons twists and turns have renewed my interest and respect for Lost. There were no fillers due to the (mostly planned) reduced episode count and even with the writer's strike it was a solid season. There were really only 2 hours lost to the writer's strike anyway, which ABC has stated they will "give back" by giving 1 extra hour to the next 2 seasons. The quality of the show this season more than made up for the reduced episode count. What is planned for extra features is below, it is subject to change since it wasn't released yet. If you want to see more info for yourself on planned extras, run a search for TV shows on DVD, you should be able to find the site I got my info from.
