DOA's the main problem here yeah, I can imagine a lot of companies wanting TN for Nioh and Capcom or PlatinumGames wanting TN for that and also NG, with DOA...well, maybe Bamco? Sega would be a decent option but given that we still know nothing about that VF announcement they made months ago after which they stayed silent, Bamco's the only good option that comes to my mind after them.
I wouldn't want Bamco to acquire Team NINJA. I don't need their "No Frame Data" and "Nobody Plays Tutorials" mentally in my fighting games. DBFZ was cool, but Bamco's stubborn, out-of-date mentality to their 3D fighters is exasperating. The company that I'd like to acquire TN would either be Microsoft or Square Enix (though I don't know if Squeenix would be willing to give TN another chance after Dissidia NT.)
