Update 2 (Mon 17th Aug, 2020 12:30 BST): We've spoken to Ruud van de Moosdijk (again) and he's made it clear a Switch version of Killer7 was "never" in development under Engine Software. Here's exactly what he had to say:

It was never in development. When we started working with Suda-San on the PC version, it was an on-going discussion during development, but as I said - in the end, the decision was made not to work on a Switch version. But since it was part of the initial discussion it was still internally listed as "Killer7 - PC/Switch project" which is where the confusion came from.

So what are the chances of Killer7 coming to the Switch in the future? If it is happening - Engine Software apparently has nothing to do with it:

It has not come up in conversation, but both Suda-San as ourselves are quite busy at the moment and with all cancelled events we have not had the chance to catch-up. Never say never, but if it is in the works, it is not in the works with Engine.

Update (Sun 16th Aug, 2020 07:30 BST): Engine Software's owner & VP of development, Ruud van de Moosdijk, has reached out to Nintendo Life, and unfortunately, it doesn't sound like Killer7 will be coming to the Switch anytime soon. The project he's working on is not Killer7 for the Nintendo Switch and the banner on his LinkedIn page should have been changed. Sorry folks!

Without saying anything about unannounced projects, the unannounced project I am working on with a prolific Japanese developer, is not Killer7 for Switch sorry.

The banner on LinkedIn should have been changed, as in the end we only did a PC version of Killer7.

Original story (Sat 15th Aug, 2020 05:05 BST): Earlier this year, legendary game designer Suda51 said he would love to bring some of Grasshopper Manufacture's older titles to Nintendo's latest system but it wasn't his decision to make. One mentioned was the cult hit action-adventure, Killer7. It made its debut on the GameCube and PS2 in 2005 but a re-release on Switch is "pretty much" out of his control, last we heard.

Now, YouTuber Doctre81 - perhaps best known for uncovering evidence of The Witcher 3: Wild Hunt - Complete Edition, well before it was even announced for Nintendo's hybrid platform - has found a LinkedIn page of an Engine Software employee making reference to a "Killer7 Remaster" for the Switch. Take a look below:

As noted by Doctre81, Engine Software teamed up with Suda51 in 2018 and released Killer7 on the PC. The profile description also mentions how the employee is a producer on an "unannounced title" in collaboration with a "prolific Japanese game designer", which is believed to be - you guessed it - Suda51.

One other Suda51 classic that might be making a return is the original No More Heroes after a rating for it was discovered on the classification board in Taiwan earlier this month. Would you like to see Killer7 make a comeback? Tell us below.
