I bought ARCHIE #8 recently , and , contrary to what I had internalized , it still had Golden Age Archie reprints .
  I was glad . 
  Will it keep having them ? Are these stories which have already been reprinted in Archie book collections (thus already " mastered " , if you will , for reprinting) ?
  Do the Jughead and B&V titles feature reprints too ?

Jughead does — who knows for B&V ... we'll see when it comes out ...

The reprints (they're also in the back of JUGHEAD) mostly previously appeared in Dark Horse Comics' ARCHIE ARCHIVES (or ARCHIE'S PAL JUGHEAD ARCHIVES) hardcovers, and some of them in various "From the Vault" sections that have appeared in Annual and Jumbo digests in recent years. The new B&V isn't out yet, but I'd assume that they would have vintage B&V reprints in the back as well. It's anyone's guess as to whether ACP will continue the policy of reprints in the back, as there seems to be a general dislike expressed by most people who've commented on it.
