When he wrote that the only thing anyone knows for sure is that nobody knows anything, William Goldman was referring to the film industry. But he might as well have been writing about IT.

This article appears in the March 07 issue of PC Advisor , onsale now in all good newsagents.

As usually happens at the start of a new year, PC Advisor's inboxes have become deluged with press releases that claim to see into the future – specifically, how the IT industry will evolve in the 12 months ahead. And pretty much the only thing we can say for certain is that, a year from now, most of these will have been proven hopelessly wide of the mark.

Who among us saw that YouTube would be the big success story of 2006? Or that, in the games-console market, the main plaudits would go to the Nintendo Wii, the least technologically advanced of the new machines?

This time last year, most of us were gearing up for the war of the HD (high-definition) formats, expecting the massed forces of Blu-ray and HD-DVD to meet in a ferocious, bloody battle. As it turns out, we're still waiting for the first standalone HD-DVD PC product, and Blu-ray has arrived in dribs and drabs. In this month's PC Advisor we look at Lite-On's addition to the market: the LH-2B1S is a fine drive and an interesting purchase. But this is only the third such product we've seen this year.

We can make some predictions about general market trends in 2007 – after all, the arrival of Vista gives us a good blueprint. We can expect more 64bit applications. Games programmers will start to test out the graphics capabilities of DirectX 10.0. And perhaps we'll see some proper uses for those fancy multicore processors Intel and AMD have been pushing.

The internet is sure to play an increasingly significant role in our everyday lives. Will products such as the Devolo dLAN 200 enable us to do away with wired connections altogether? And will the likes of the Noxon iRadio finally convert the masses to the joys of internet radio?

You'll have to wait and see. The only thing we can say for certain is that, if it's in, it'll be in PC Advisor.
