I read over at the Adobe website that the CS6 products will still be available until the CC (Creative Cloud) products become available sometime in June 2013.  However, in other statements they said CS6 will be available indefinitely.

Since Adobe hasn't made it easy to find the link to purchase upgrades or full versions, here it is:

http://www.adobe.com/products/catalog/cs6._sl_id-contentfilter_sl_catalog_sl_software_sl_creativesuite6.html?promoid=KFPMZ

Click on Buy where you can select either full version or upgrade and what you are upgrading from.

I'm not switching to the CC either.  It's a waste of money.  I'm planning to switch over to Corel for some of my programs while others I'm stuck with until I can find better alternatives.  I started with CorelDRAW back to Version 3 (on floppy discs).
