I cannot seem to find Wh20 listed on either Bay area or planetary, anyone else found this?

Chillax, AB. 

Based on the last releases they will both show up once Rick (the owner of both websites) updates it later on.

He usually makes a post on rgp as well just after doing so, so you can check there as well.

If you are really keen just keep checking at regular intervals today and you might get lucky with an early website update, but especially tonight as it gets closer to the "official" release time.
