The introduction of the Sorcerer seems different than the Druid, as it has received its very own "intro screen" painting, rather than just a screenshot.

I'm speculating here, but it seems this particular Sorcerer may also be a main nautiloid-type character, available for selection in the Camp. As a result, all that Sorcerer's game elements were added... which takes a longer time and Larian wanted to get it squared away before some of the other classes.
