There probably won't be an English release even though it could sell decently as Ippo is quite popular in the west but nothing stops you from importing the game as the PS3 is region free and there are plenty of sites that provide this service.
This will hopefully keep you satisfied till the next season of the anime finally comes out.
Here are some pictures of other Ippo games over the years.
The GBA version.
The awesomeness that is the anime.
