If I have to endure years of my non-cyberpunk friends talking about how Snowcrash feels like a rip-off of Ready Player One, then I will flip tables.

Despite the jokes, HBO tend to do a decent job of this stuff. Ignoring the shitshow that was GoT after season 4. The Wire, The Sopranos, Westworld... probably better in their hands than, say, Netflix.
Game of Boners - Aiden Gillen returns to his brothel to make use of his Littlefinger namesake.
The Sopranals: Gandolfini enters Bada Bing! through the back door
etc. etc.
Which is to say, HBO actually seem to be quite tasteful with this while also being gratuitous.
The Raft is still new 'territory' for most sci-fi, the closest we ever got was Waterworld with Kevin Costner.
Reason remains sufficiently insane as a weapon to this day (like Project Pluto). Raven is, however, a bit 'old' now and I think may need an upgrade.
Smartwheels are still out of reach and car surfing still is cool as hell.
RatThings are just on this side of lovable in a Cthulhu-esque sort of way, so I think it'll be good merchandizing (which, reading that back, really drives home the dystopic feel of 2020)
The metaverse is, yes, very old now. I'll be interested to see how they deal with it.
Uncle Enzo and L. Bob Rife scream out for parallels to Bezos and Gates. So, not really 'new' but still fertile ground.
All that said, the first chapter is literary genius and it would be extremely difficult mess up. All the build up to find that Hiro is a ... pizzaguy. So good.
