Sony Marine Pack MPK-PHA / MPK-P9

Hello

I am looking to buy a marine pack for my Sony P7. Last year's model, MPK-P9, is extremely hard to find! This year's model, MPK-PHA, is listed as supporting the new P8 and P10, but doesn't say if it's backwards compatible for the P7. Does anyone know if it is or is not compatiable?

Thanks for the help!

The P10 is smaller than the P9 so I doubt the housings would be interchangeable, I was looking at the new P10's last week .... look good!
