Does a NEW PTHD11 purchase include PTHD10?

[WombatStudio.Org]

Since I no longer have the option of the CPTK add-on, my only choice would be to buy PTHD.

If I buy it NOW, I will get PTHD10 with the complimentary upgrade to PT11HD, but if I wait and all that is available is PTHD11 will I also have the ability to download and install PTHD10?

I'm currently running PT10 so I have a bunch of plugins that would only work in a software that supports RTAS ... and there is no upgrade path from PT10 to PTHD11 ... unless you consider buying the CPTK now for $2K plus the upgrade at $1K which comes in at $2000 cheaper than buying HD Native w/Omni. BUT, I don't have $5K right now let alone $3K.

OR, can I pick up a CPTK license on eBay in a year for a cheap price and still have the option to upgrade to PT11HD for $999 and still get PT10&11HD iLok asset?
