There will be at least 1 Japanese team, if not 2, but Crazy Raccoon is honestly probably the favorite if they choose to come back due to their popularity, and maybe Zeta if there are 2.
There will definitely 2 Korean teams, if not 3. GenG seems like a decent bet since they were successful at one point and they have a proven track record in LoL. If there are 3... idk, NongShim? They have a big company backing them and could potentially have the best year of any team in 2026.
I think Boom will represent Indonesia. Bye bye RRQ.
And then Thailand and PH? Honestly one or both of these regions may get left out, likely Thailand. PH I think will be NAOS at this point. No more family business. I don't see Full Sense getting partnered. Maybe Xipto?
If I had to guess though, there would be 2 Korea (T1, GenG), 2 JP (CR, Zeta), PRX, Boom, NAOS, Global.
