I'd say it's not worth the wait.
There is always something better coming out so if you keep pushing it back, you will never buy anything.
I bought my first HD television in 2011 (50" with 3D), another one for the bed room in 2013 (47") and finally my 4k TV in 2018 (70").
All of them are still in use and who knows, maybe I buy another one in 5 years.
