65" LG C5 or wait for C6?

The 65" C5 is currently on sale ($1,399 USD), which I will have a 60-day window to price match if it gets any lower. I know the 6-series is coming soon, but I imagine that it won't go on sale for quite awhile.

I am wondering if the 65" C6 will be that much better than a C5 on its current sale price?
