If you're upgrading from a card more than two generations ago, better to upgrade now, then wait for the 8k series. However if you're gaming only on a 5** or 6k series, then you might as well wait for the 8k series. Its rumoured to be early Q1 2013, however by the time its in stock, and within a reasonable price, with all kinks worked out, I agree with Simon, you might as well again be waiting for the next generation.
