So, I have Poser 8, I can buy the sidegrade to Poser Pro (previous version) within the next 30 days for $199. I will get Poser Pro licence and then, when Poser Pro 2010 is released, a free full download and licence for that?

I.e.
I have one Poser 8 licence now.
If I get Poser Pro (using the P8 licence to sidegrade) I will have a Poser Pro licence - do I still have a valid Poser 8 licence?
When I get the free download of Poser Pro 2010 will I get a third licence? If so, are the other two still valid licences in their own right?
