I just curios: What is the difference between the BDP5200 and the BDP6000?

If I compare them on the Philips web site the only difference is that the BDP6000 has "CinemaPerfect HD".

But why does the BDP6000 is much more cheaper than the BDP5200 (see German Philips Shop)?

Can somebody explain in detail what the real differences are?

Maybe Philips can also post a spread sheet with the differences of the 2010 and 2011 BDPs...
