Rockstar was the publisher of Max Payne 1 and 2. Max Payne 1 and 2 were developed by Remedy/3D Realms. So Rockstar is new to developing Max Payne.
I know this post is about a month old, but I wanted to clarify the situation.
Remedy developed Max Payne, 3D Realms published it. Then Rockstar ported Max Payne to the PS2. I own both of these games, and the PS2 copy reads: "Developed by Remedy/Version by Rockstar Canada." After the port, Rockstar bought the rights to Max Payne from 3D Realms. Then they published Max Payne 2 and ported the title to consoles. So they have worked on the Max Payne games in some compacity.
That said, the real question mark here is the absence of Sam Lake. He was the original model for Max Payne, and the author of both games. He also followed Remedy to write Alan Wake. So he won't be writing Max Payne 3. That's a little worrisome.
