I want to know the answer to the following question:
How many versions of the CECH-4000 were made?
All the background I'm provided with is that "Three versions Super Slim model were revealed: one with a 500 GB hard drive, a second with a 250 GB hard drive which is not available in PAL regions, and a third with a 12 GB flash storage that was only available in PAL regions.". Is that enough to answer the question?
Answer: yes
