KRÜ only seems like a good organization long term for LATAM unfortunately. Heard some shady stuff about orgs like Leviatan, SixKarma and Fusion so honestly think Riot wouldn't take a chance on them but we'll see.
I also heard one American org was interested in investing into LATAM which makes that quite more likely.
My hot take is:
(6 NA teams) C9, Optic, TSM, 100T, SEN, FAZE
(2 BR teams) NIP, LOUD
(2 LATAM teams) KRU, INFINITY
I don´t think they'll choose two teams from LAS unless LEV goes to Mexico or some other country from LAN
I doubt FAZE could make it because of the finances, but idk
*Riot won't give less than 6 teams to NA until they understand Valorant is achieving that all regions have real contenders and potential
