I mean I'm not sure any of these will end up world class, but these are who I'd expect to see in or near the squad in 2024;
There's Liam Mudenda of course, who's one of the best we've had at his age. He'll be 17 in 2024, but idk what his plans are - He's too good for us. But then his grandfather is Jacob Mudenda so I guess they'll be embarrassed if he flees to England or wherever.

Panashe Taruvinga will be 17 in 2024 as well.
Sean Bennet from Peterhouse (younger brother of the twins) is a promising opening bat, think he keeps wicket as well?
Tyde Stirrup from St John's looked really good a couple of years ago as a 14-year-old. Hit a big big century against Falcon in the last game before Covid arrived.
Kohl Viljoen is a keeper-bat. Related to Dirk apparently - presumably his son?
Matsikenyeri's son is a similar age as well, I've heard he's good, but I've never seen him.
Ben Williams. Again, pretty good family experience haha. Think he bats and bowls. He's at Falcon.
Taurayi Zimunhu from Falcon as well.
There's several sets of brothers. The Martell's, the Patel's and the Nyamhuri's (SA-based). Think they are all pretty much all-rounders, as usual at this young age.
Dylan Nzvenga Another from Falcon
Brandon Sunguro, opening bat was at Prince Edward. Think he's gone to South Africa though on scholarship.
Saxon Pettican - All rounder. He's one of those annoying kids that is good at several sports and very academic though. Not sure he'll stick with cricket. Played in the NPL for Queen's last year as a 15 year old.
As for out and out bowlers, I'm not so sure. Matt Schonken from the current squad will still be eligible in 2024 though.
