"(later to split and become Remedy and Mad Onion - which became Futuremark again"
What are you talking about ?
To my knowledge Remedy and Mad Onion/Futuremark have never been one company Remedy where one of the founder of Mad Onion/Futuremark and they licensed them the Max-FX engine(Wich was not later sold to Take 2, they "only" sold them a perpetual license).
Remedy had begon early development on Max Payne before 3D Realms entered into the picture, they were actually working on three games at once but 3D Realms adviced them to concentrate on one and Max Payne(or Dark Justice as it was known as initially) was the one 3D Realms and Remedy picked.
3D Realms involvement in Max Payne was a result of them(under the name Apogee) publishing their(Remedy's) first game Death Rally.
"Unless this "new game" is two months away from release or 3DR are shopping for a publisher for it, then they have once again made the mistake of announcing something way too early. I'd have thought they would have learned not to talk about a project until it's release is imminent. Why do they need to create a buzz at this point? What's the real motivation here?"
The game is still unannouced remember we no nothing about it.
