Most probably Kuku will be acquired by Blacklist, given that he's a long-time friend of the org's CEO. He could easily use that as a leverage to further his interests and be in a team that has the capacity to acquire great players since they have the budget and the platform that not many new orgs in SEA has. It appears that not many orgs in the region are prioritizing Dota 2 anyway, so the options for these released players are very few.
It looks like it as I also saw this leak mentioned on Reddit and this was their potential roster on Blacklist.
3 out of 5 member of former TNC Pro members, I'm also expecting this as well given that Blacklist is trying to build an all filipino team representing Philippines and take the chance for a full Filipino team to win the TI. I don't have any news about other TNC former members, Did they quit dota? I haven't seen them in the scene for a while now. If this line up becomes a reality, I'm sure Filipino will be on hype as hell. Those who quit dota will surely get interested on what's happening to dota given that the community and the pro scene is still active.
What iteration of TNC are we talking about here? The first TNC that made it to their first TI, or the one with Armel and Gabbi? Armel is still actively playing, Gabbi is also looking for team, Eyyou is in a local team (Polaris if I can remember), and jessievash is now in Valorant. It's just that the teams that Gabbi, Armel, and Eyyou is joining aren't really accomplishing much, while their former teammates are finding luck on placing in main stage events that's why we're hearing of them more.
From the above list, I think it's possible that they acquire Eyyou again as 5 and captain. The man still has the meta, the plays, and the overall wits to compete professionally, just that he's always teamed with other players that aren't as hungry as his former TNC mates.
... or they can always go back as 5 with N0tail, Ceb, and Jerax (Taiga hinted that the members of the old OG squad might return to active pro scene come 22-23 DPC season). N0tail is the only one I'm quite unsure of whether he wants to go back and compete again. The dude's chillin' and enjoyig creating vlogs and all that stuff.
Ceb also mentioned that NoTail may need the longest time away from competitive DOTA since he was doing this the longest. So, we may still not see NoTail this DPC season. But if they do decide to team up again, are they going to be the first team or the second? The current roster is performing rather really well. They won a major and a few tournaments. It would be a waste to disband them or relegate them to the second team. Topson is still top tier as we saw last TI. Ana is still good and we also saw Ceb play in stockholm. It will be a hard decision for OG management if they all decide to come back.
Possibly another org, or a sister org if you may. OG already left ATF as a free agent (though they haven't announced it yet), and it's up to Ammar whether he'll stay with OG or not. That spot could easily be snatched by Ceb if Topson and the 3 other old OG members aren't wanting to play in the 22-23 season. Possibly they will not let go of Taiga and the gang of new OG members. They'd just look for replacement for Ammar first.
