They're releasing their next game in May, prelimenarily.

ZERO PARADES: For Dead Spies is an RPG looking to be very much in the same mechanical, and similar graphic/art, style as DE. The description on Steam is:

"You're a brilliant but tormented operant on one final desperate assignment. Gather your broken network, untangle a web of lies, and prove yourself on the world stage - or blow it all up again."

This also sounds very DE to me.It is NOT, apparently, taking place in the same world, however.
