I'm trying to think of it in terms of, "What if that first Iron Man film had been stretched out to 13 hours? At what point in the narrative would we get to the point where he dons the red/gold armor for the first time to defend the Middle-Eastern village? Episode 8 or 9?" That seems like a reasonable point to expect him to upgrade costumes.
I'm guessing the suit is going to be like the costume in Smallville.
I'm still guessing that Wilson Fisk blackmailing Melvin Potter back into a life of crime which brings him into conflict with Daredevil will be a subplot running through a few episodes, and it'll be at the resolution of that when Potter makes Daredevil his red costume as a token of gratitude. The question is just how long it'll take for that plot thread to resolve.
Well, this could be totally wrong, but according to IMDB, actor Matt Gerald, who plays Potter, only appears in episodes 8, 11 and 13. So I would say the absolute earliest we see the red suit is episode 11, if that's accurate.
I'm guessing the suit is going to be like the costume in Smallville.

All of this is exactly how I feel.
I'm even looking forward to this more than AoU.
Quesada, Loeb, DeKnight, and costume designer Stephanie Maslansky talk more about the evolution of Matt's costume:

Theyre gonna wait til the last episode then have him spraypaint a DD on his chest. BOOM!


IMDb is not always the most reliable source when it comes to casting info (especially in TV shows).
