Founding members Stefan Lagergren, Jörgen Thullberg and Anders Holmberg reunited for a one-off gig for the release party of the Swedish Death Metal book on January 26, 2008. The last founding member, Johan Edlund, did not participate, stating in some interviews that he doesn't want to have anything to do with Treblinka anymore; moreover, as he said in 2008, Treblinka "was an extremely bad name". The brothers Erik "Tyrant" Gustavsson and Per "Hellbutcher" Gustavsson of Nifelheim replaced him for this show.

There is also a two CD bootleg compilation called Treblinka. The first disc features the single and both demos (in reverse chronological order). The second disc has a live concert captured in Stockholm on April 7, 1989, and a rehearsal recorded on January 3, 1989.
