I haven't made it to the Bianchi store yet, but here is a clean used Fretta at Rakuten ********************R)BIANCHI FRETTA ???? 18??? 2012******************************


>Edit< I went to the Bianchi store after lunch, and they told me the Fretta was discontinued. If you want one, you will have to settle for a used bike. For a new bike, the Birdy is now the only option.

FWIW, the Birdy standard with the straight frame has been redesigned a bit, the fork and rear frame are stronger, and the straight top tube actually tapers out to increase the stiffness where it is welded to the seat tube. Of course, you can also get the monocoque versions as well.
