Guess that makes it really real: The HTC HD2 (aka the Leo) has made an appearance in the an in-store catalog for the UK's O2 network, and said catalog was slipped to Engadget Mobile. They're also hearing that the rumored Oct. 12 launch date might have slipped to Oct. 26.

Engadget also points out that the promo shot show the standard Windows Mobile 6.5 home screen instead of that new TouchFLO 3D goodness we've been seeing, which is interesting. Maybe that means something, maybe it's just promo shenanigans.
