The other day, I fairly confidently prediected to a friend that Powers would be the next 4e book after Banestorm based on my reading of the occult ruins and the trade pamphlet that came with my shiny new copy of GURPS WWII. And I confidently predicted that it would be out in August or September.
The 4e version of Traveller is next up in August.
I may yet get my September prediction, but I doubt it, given the mumblings of a book every other month.
So I need to work on that Kremlinology (SJ Games) skill a bit more, because I just blew my roll. ;)
[I really need an RPG icon.]
