The only IT (other than ITE) size that they will release this year is 205/50/15 and thats not even a great IT size.
All the other sizes slated for release this year are 17s and 18s. This info comes from a Kumho dealer.

Compare this to the first sizes of the new Hoosier (225/50/14, 205/50/15 and 225/45/15) and you get great insight into which tire manufacturer is focused on the IT community.

I think I'll even post this in the discussion forum and see if I can drag up a good argument.
