Update are through to April 2014, so no rush.
Even when it does come in all honesty it probably won't make that much difference (certainly not to me), there are people who get infected with monotonous regularity no matter what OS they have. There have long been security holes and exploits (even those discovered by MS) that remained open for some considerable time, there are still unpatched vulnerabilities.
I have for a very long time taken responsibility for my systems security in the pro active measures I take, the security software I use, the habits and practices I follow and in all of that time not one single alert/infection in all of that time. It is quite possible to secure your system no matter what OS you have it isn't your all doomed.
I won't be rushed into any decision, Had I not bought a netbook then I probably wouldn't have win7 either and win8 I was actually looking forward to. But that turned out to impress me even less than win7, so I may well be waiting for win9 a.k.a. windows blue, to see if reality lives up to the usual MS hype.
Hell how knows my next OS update could be Linux or even Android or Firefox. But I know one thing for sure my security practices, backup and recovery strategy will be in place to recover from any eventuality.
