Does samsung update its models every year?

Samsung model cycles usually refresh around late march to mid-april, but 65" models usually don't appear until at least mid-summer.

They announce new models at CES in january. Those sets don't actually come out until march or april. Traditionally, their 65" models are out later than 55"/60" counterparts, hence my estimation of late summer on the arrival of a "65FS8000."

As far as the uniformity/other issues go, I wouldn't hold my breath on a 2013 equivalent being an improvement - Samsung's LED lineup in general is known for its issues, even moreso in their 65" models. They usually suffer from poor uniformity, panel issues, banding, etc. The 65" 8000 models have suffered from these issues for the past three years (UN65C8000, UN65D8000, UN65ES8000).

Not trying to kill your hopes and dreams, but black levels really haven't been making giant leaps. Let's put it this way, the flagship from 2010 had a black level of .05 and this years flagship model has a black level of .04. It really isn't much of a change to say the least.

I'm just saying, buy when you can and don't keep on waiting for that future product to come out that will solve all issues. We've all been waiting for those LCD's to come and they never have arrived. The days of flawless TV's sorta ended with the death of the CRT. Even the new OLED displays still have their own fun uniformity issues and black issues.
