As you may (or may not) have seen by now SNKP have put some time and effort into creating different coloured costumes for each character. (From what i understand each character has a total of ten colours.)
So far some of the ones that have really stood out to me have been Robert in a Terry colour scheme, Terry in a Robert colour scheme, Raiden in a Venom colour scheme, and i've read Kensou also has a Duo Lon colour scheme.
What is interesting though is Yuri's choice of colour also affects what kind of clothing she is wearing on her legs.

Also Taiwan has had a location test this past Friday, from what i've been reading there will also be another Location Test in Japan during this weekend so hopefully more videos will pop up fairly soon. No word on whether K' will be playable yet.
Check out the rest of the videos here.
