This may come as a shock to some but it seems HL2 is going to be delayed... who couldnt see that coming...

According to Vivendi, the packaging and distributors of Half Life 2, there is going to be a slight delay in the release of the afformentioned game.
Although Valve has neither confirmed nor denied this rumour, many people thought it was likely due to Valve's track record of project delays and lack of information.
We should still see this exciting game within the year, but it may be slightly later than the September deadline officially announced at E3.
