You can still get CS6, but CC, which was equivalent to CS6 when it started, is coming up on a year old, and you pay 20 dollars a month to have access to it. CC will continue to get updates. When you stop paying your 20 dollars, you stop having Photoshop at the end of the month.

There was actually a $10/month offer for Photoshop CC and Lightroom CC (expires 31st March) - I got bought it for my other half. At $120/year it's cheaper than buying Lightroom in full here in Australia.

The frustrating part is that you can't pay for the full year up-front for most Creative Cloud plans.
