> Can you find out if it offers more PCIe lanes than the e5500?

PCIe controllers in a SoC are not dependent on the SoC's core. If I take your question to mean whether the SoCs incorporating the e6500 core will have more PCIe lanes than the P5020 and P5010 then I'm afraid no such information is public yet. The only e6500 based SoC that got announced so far is the T4240, but no too specific information on that.

From the press release:

"Freescale will provide more details regarding the T4240 product later this year. The device is planned for initial availability in early 2012."
