No they do not if you like look at the topic on this i posted about yesterday.
Staff promos never came in the prerelease kits.
A tgey use to ship pikemon prerelease kits in a regular box with 8 kits 1 energy box 1 booster box. The staff promo would be in the energy box.
The new way is a special display box that has only 10 kits in it. They put that box inside a normal box along with a box of energy and 1 booster box. Then they ship 4 staff promos, 1 of each promo staff card in a seperate padded envelope before you even get the prerelease kits normally 3 days before
