"Yesterday Sony released the Hot Shots Golf 5 demo on the Japanese PlayStation Store.
In other news, we may be seeing a Lair demo, hinted at by the image that popped up yesterday. Well take it as you will, we'll be sure to let you know when the developers confirm or deny the demo.
(note) Then again guys this is PSU.COM (Killzone 2 next month anyone)?
So I wouldn't get my hopes up yet.
