Earlier this morning, the WE 2012 demo was made available on the Japanese PSN store.
You'll be delighted to hear that the Japanese PSN store has updated and now includes the second demo, rather than the first.
Here is some confirmation if you want it - you'll notice that it says Ver. 2!
Last night, you would have noticed that the US PSN store did update. However, it was the first demo which was made available, rather than the second one.
The PS3 demo will hit the UK PSN store later today from 5pm.
