Sounds like you need a WiiPS3.
If you also need to buy a Blu-Ray player, it would be silly not to get a PS3. The PS3 is the best Blu-Ray player on the market right now, and the most advanced due to the fact that its firmware is upgradeable. Case in point: The firmware in the PS3 was just recently updated to 2.20, which added support for Blu-Ray LIVE, and as a result the PS3 is the only Blu-ray player on the market that supports that function.
Hell, why not buy all three!
and end the fanboy wars!
