There is now some more concrete details for the Gunman Clive HD Collection, which is a pairing of the first two games in the series, which were originally on 3DS. According to the developer Bertil Horberg, it’s set for a September 3 release, and will come in at $3.99 — essentially netting you each game for two bucks.
This is if everything goes “according to plan” and all of the certification processes go off without a hitch. Horberg states that there will be no Cross-Buy benefit or discount for people who own the 3DS version.
