I actually don't mind DLC characters this time. And the reasons why I'm giving SNKP a pass are:
They're actually releasing characters that we want for the most part. Yeah, it sucks we don't have Yamazaki, Blue Mary, Vanessa, Gato, Oswald, etc. But, we are getting EX Kyo and Iori, and Shin Mr. Karate back which is a happy middle. Compare this to UMVC3 adding characters about half of which no one gives a shit about.
The other reason; I see it more as a donation to SNKP. They're not going to be making very much off of DLC, so I see it more as an extra thank you to them for making KOF13, and focusing on Netcode and features that we want, and as an indication that we want more.
Plus you get stages exclusive to those characters too. So I might just buy EX Kyo if his stage is badass. Compare this to Crapcom charging $3 a piece of hideous DLC colors for 3SOE.
