New upgrade policy with CorelDraw X6?

Today I found at a  website of a software shop, that Corel will change the upgrade policy with X6 so that it will not be possibe to upgrade from CorelDraw Version X3 or older! Only X4 and  X5 will be accepted for upgrading - otherwise you have to buy the Full Version!

Does anybody knows or heard of it if this is the truth? It's an important question for a X3-user like me who waited for X6 ...
