I was a GM on Seattle MUSH, which is where I got this handle, oh, 25 years ago or whatever it was. I ran the NAN, Council Island, First Nations, etc.
There is/was an effort to code a 5E MUSH (Deep Shadows MUSH) that started about 4 years ago. Their last Twitter update (@deepshadowsmu) was 7 months ago, so who knows how active that is.
The video game licensing for Shadowrun is complicated, but the short version is that Microsoft holds the license for Shadowrun video games. (They've owned the electronic rights to Shadowrun since purchasing FASA Interactive 20 years ago.) No offense to Microsoft, but they're a lumbering beast and it takes a lot of nuyen to wake them up. It's entirely possible that Microsoft would be willing to license the electronic rights like they did to Harebrained and Cliffhanger, but it's no guarantee either. (Technically there might have been a middle step involving Microsoft licensing to Smith & Tinker first, then to Harebrained, but I'm fuzzy on that point.)
Also remember that Catalyst is just the publisher. The actual intellectual property of Shadowrun is owned by Topps. I don't fully understand where the IP lines are drawn, but I think you'd need Topps to sign off on anything involving the Shadowrun world/setting, and Catalyst to sign off on anything that references the rules or systems that Catalyst created. So now you have three parties at the table representing various components of Shadowrun IP, and you haven't even involved any video game developers or publishers yet. In theory Microsoft could develop it and publish it themselves, but there's a lot of inertia there. Plus there's probably the institutional memory that their 2007 Shadowrun first-person shooter didn't hit it out of the park (sales figures in the low six figures), so they're probably more interested in licensing than investing a ton of time and effort into it themselves. But that means you need a developer and/or a publisher at the table too, and things get complicated quickly.
(Wak or anyone who knows the inner workings better than I do, correct me on this.)
I'm not saying it can't be done; it can, and hopefully one day it will. Maybe Cyberpunk 2077 will inspire Microsoft to dust off their IP and shop it around, but it's not as easy as Person A calling Person B and making a deal between two people.
