Gameplay demos from E3

Does anyone know when we'll be able to download any of the gameplay demos that were at E3 in the UK? (espescially the Sleeping Dogs 1)

I doubt any of them will be playable until a week or so before there release.

Yet, I have not make any donwload of the gameplay demo from E3, also not find any way how to make downloading of any gampeplay demo on E3. I think there will be time for such kind of demo.
