The number I heard was 8 airframes to start up the 757 European operation. It will also be where they go first (early 08) with the first Memfo-based airframes showing up in early 09. The location of the European domicile is what's holding up the next big bid - the training letter for that will include 757s to Europe so they have to have everything nailed down before they let the crazy masses bid on it.

This info is almost two months old, so it's probably been changed 7 times since then.
