I put the question on the German ADOX-PHOTOIMPEX Photolaborforum where the new and coming ADOX 400 replacement for Agfa APX 400 is discussed. Mirko answered that he didn't rule out the possibility for a 220-version but for the introduction they have to concentrate on 135 , 120 and sheet film sizes. If we continue to beg, pray, hope and threaten there may be result one day.
I am enclosing a link to his answer so start looking for your old German dictionary and gramar. Good luck !
