Our friend Asapon (japanese professional modeler of several figure masterpieces) told us that in november Yujin will release a gatchapon R Shooting Video Game History Gashapon: a series dedicated to some of the most famous shoot'em up from the 80s and 90s! Coloring is still in progress and we look foward to see the definitive colors of this must have gatchapon series!
Update: Mark points out that NCSX started preorders for the  SR Series at the beginning of august. If you are in Europe you can preorder here. If you are not scared by japanese language you can try your luck here with tons of shops selling this collection at a really good price!
