That isn't to say Kojima-san wouldn't like to actually see that happen, but he isn't putting the project together. The game designers twitter says it was "mistranslated from our side."
The new Fox Engine is being used to put Metal Gear Solid 5 together. Dropping the original game into would create a whole new experience without a doubt.
"Regarding the rumor from yesterday, checked the data recording of the actual interview. It was mistranslated from our side," Kojima-san. "Chris, my interpreter answered in different nuance that made this consquence. I on the other hand, answered w/ bit of lip service."
"I answered "You (the journalist) wanted me to do MGS2 on Fox Engine but I cannot do. I wish if only someone could make MGS1 on Fox Engine," he continued. "However, Chris mistranlated as "Personally he would like have MGS1 on Fox Engine, so he try to find someone right now to do that." NOOOOO!!!"
"The journalist wasn't wrong. We are deeply sorry for the misinterpretation on our side," he added. "Well, if there's some creator or team in this world who has love and passion to remake "MGS1", I would love to ask for it."
While depressing that it's not going ahead, at least Hideo Kojima is definitely open to the idea. Metal Gear Solid V: The Phantom Pain is being developed for Xbox 360, PS3, Xbox One and PS4 - it takes place after Peace Walker chronologically, and before Metal Gear Solid.
