I keep a close eye on mine. I had a lot of sludge under the cap and replaced mine as soon as I bought it in late 2016. I live in the mountains where we get a lot of freezing temps and snow, and drive a very short commute. I don't have significant sludge after 3.5 years. I pull off the vacuum lines and oil cap periodically to check, and even pulled off the valve cover twice to inspect. I think two years is too cautious, unless you drive tons and tons of short trips in cold weather without getting the car warmed up completely. I was prepared to replace mine every 2-4 years but haven't seen the need.
If your car has never had the CCV replaced, it's time to do it ASAP though, and do get the winter version even if your car didn't have it from the factory. Unless you live in Arizona or Florida.
