6700k or wait for 6800k

With Pascal/Polaris fast approaching I'm thinking about upgrading my platform in preparation.
I'm leaning more towards Skylake, but getting extra two cores with Broadwell-E sounds tempting. It would be somewhere between 140 and 220€ more though, depending on whether I'd buy a cooler as well. Not sure if it's worth paying that much extra.
I don't do any video related tasks on my machine either.

Any opinions are appreciated.

If productivity is not an important task for the machine, than more cores is a waste of money.

Having said that, even Sandy Bridge is still perfectly capable for gaming.
