Dragon Ball Kai is going to air in a Portuguese channel called "SIC Radical" and it won't be dubbed (lucky them), though, instead it's with the original Japanese audio and with Portuguese subtitles.
If anyone wants to know what's written while Kakkarot/Raditz are talking then here ya go:
Rukura wrote:Goku: I wanted to watch Dragon Ball Z, but I'm tired of those old and worn-out from the original episodes.
Raditz: But now you have Dragon Ball Kai.
Goku: Dragon Ball Kai?
Raditz: Yes, Dragon Ball Kai.
Goku: And what's Dragon Ball Kai?
Raditz: You don't know what Dragon Ball Kai is?
I already said I didn't!
Raditz: Look at that, this one doesn't know what Dragon Ball Kai is...
Goku: Are you gonna tell me what Dragon Ball Kai is or not?
Raditz: Dragon Ball Kai is the remastered version of Dragon Ball Z.
Goku: What else?
Raditz: And re-edited by Akira Toriyama. (<---- -_-')
And it will air in SIC Radical.
Goku: Oh, now I know what Dragon Ball Kai is.
Wait, tell me one more time.
Remastered, SIC Radical and what else?
Promo card: Coming soon
Dragon Ball Kai.
As of now, they're still airing this advertisement.
