Just wanted to share with you, that the vinciDuino Rev C (a Leonardo clone with the same form factor as and Arduino Pro) has been released. It is tested and everything is behaving as expected. You can now use the Arduino IDE 1.0 in its Leonardo flavor without any changes. Also there are some very interesting features about the board. You can read all about them:
