Home Cinema: How many inputs?

[Jimmy H]

I have a query regarding finding a home cinema system. I plan on getting a DVD home cinema system to complement my Panny PX80, but i will also be getting Sky HD and, eventually a PS3 for Blu-Ray. Can you get a system with enough inputs to cope with the PS3 and sky HD. The other problem is that i will need wireless rear speakers!
Cheers.
