In a 2024 Famitsu interview, Metal Gear Solid Delta: Snake Eater producer Noriaki Okamura expressed uncertainty about his team developing future remakes or installments in the series. He felt they could not make remakes of the first two Metal Gear games or Metal Gear Solid in the same way they remade Snake Eater, and that they would have to make many new parts, and significant changes and deviations from the original games' playstyle to meet contemporary standards. As for new installments in the series, he felt this depended on the feedback they would get from the Snake Eater remake and a concerted effort with Konami to preserve the longevity of the series:

EVA's English voice actress in Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Peace Walker was credited under the name Suzetta Miñet. Fans widely assumed that this was a pseudonym as she had no other credits in anything, which sparked years of speculation as to who she could be. One of the most leading theories was that EVA was voiced by Debi Mae West, the voice of Meryl in Metal Gear Solid and Metal Gear Solid 4: Guns of the Patriots. However, while West acknowledged that the characters sounded similar, she denied she was the voice of EVA in 2015. Konami would eventually confirm in a 2024 behind-the-scenes video promoting Metal Gear Solid Delta: Snake Eater that the pseudonym belonged to Jodi Benson, who was best known for voicing Ariel in Disney's 1989 adaptation of "The Little Mermaid". Benson explained that she used the pseudonym at the recommendation of the game's English voice director Kris Zimmerman Salter, because of her association with Disney and other family-friendly roles at the time. Despite revealing her identity however, she is still credited as Suzetta Miñet in Delta: Snake Eater. The name itself was based on a pet dog Benson owned in her childhood named "Suzette Monet".
