Your talking from a technical point im talking from a historical and much more meaningful point
Historically, they were never first party characters either. And since meaningfulness is subjective, I really don't care about that aspect.
Either way, I'm guessing OP meant something about New Dante-type third party characters, not the ones that everybody wants.
We're both lawyers.
Well, your only taking one from each 3rd Party. You still have Activision, Ubisoft, Square Enix, EA, Warner Bros., NIS and Sega. You already have reps from Konami, Irrational, Capcom and Namco. That's only 4 3rd Party characters over 16. But to answer your question no I would not be upset if the last reveals were TPC's.
