Leave it another 5 years or so.
Why?
Prices will be a lot lower, tech will be better, and most importantly there may be a lot more 'genuine' 4k content available.
Buuut it's your money and your choice.

SD is going to be around for a while yet. There are a couple of reasons. One being that not every channel and production house can afford to chuck out old equipment every time the resolution goes up. You and I might have set top boxes, TVs and DVRs to replace. A productions house will have multiple cameras, studio equipment and editing suites to replace. One suite can cost upward of £100,000 to upgrade. That's ignoring the thousands of pounds of network and power upgrades they may need.
Incidentally, this was one of the primary reasons the BBC moved out of White City. It would be naive to assume that property value didn't cross the BBC's mind (after all, the site would be worth at least tens of millions), but one of the reasons was that Television Centre needed millions of pounds of upgrades to cope with the power and data requirements of the latest hardware and software upgrades that the BBC needed to make to enable HD on more channels..
The other reason is that HD (even with more advanced compression systems) takes a lot more bandwidth on any given transmission system (every system has a finite amount of capacity for channels, this is commonly known as the bandwidth). The likes of Virgin and Sky would have to cut the amount of channels they carry by a lot to make them all HD. When one of your selling points is the amount of channels you offer (even if 75% of them are crap) you'd be stupid to switch off the SD ones.
