Do we have confirmation somewhere of the exact number of teams making it? Without any info besides extra slot from winning lock-in, I'd assume it would be 3/3/4/2 (with 2 Chinese teams receiving invites). Same with champions. Do we know anything?
Well, considering that China is very likely to be getting its' own franchise league next, I think it makes some sense for them to invite their best teams to all the internationals this year. Also keep in mind that Tencent fully owns Riot which has made them partial to China in the past(along with the obscene amount of money they make over their with LoL). Makes me believe that they will do this, even if it isn't completely fair.
