Hear it from Yoshinori Ono, the man himself, (via translator):
You can find some screenshots of the two new characters, T. Hawk and Juri, over at Famitsu.
So it’s going to be a retail disc at a “discounted” price. I’m expecting $39.99 USD. Should I trade in SFIV? It does have a TIV of $36 at the moment. Maybe. There was a tease dropped about an extra bonus for those who hold onto their disc.
I’ll probably end up keeping it because of the DLC I purchased.
