Paypal is going to split ways with Ebay, although you can still use Paypal to pay for purchases, they are no longer going to be the same company.
This has to do with the stock market. Both will now be independently traded entities, with investing potential, which would have been near impossible otherwise.
That's the way it used to be before Ebay bought PayPal and rolled it into the fold. I was a member of PayPal long before I was a member of Ebay. I don't use Ebay much any more but still use PayPal occasionally.
