Oh yes, eBay have announced they are removing pro-stores & MagentoGo in Feb 2015. This is a major headache for so many businesses!
But no fear, help is here!
People that can help you migrate to Magento CE:
Yes, I can set up your OWN Magento system plus plugins like M2ePro for marketplace integration. I can also look into moving your MagentoGo design too.
Understandinge.com gives you the tools to do it yourself if you are so inclined to try.
Bigcommerce is eBay’s chosen partner for transferring your existing STORE to Bigcommerce. Bear in mind there is no marketplace integration unless you are something like Channeladvisor.
Give me a shout if you need help!
