Update: It turns out that this is a mistake according to eurogamer. What a shame but I guess no one is really surprised!
We brought to you earlier the news of a rumoured source engine 2 and how this could lead to a surprise release of Half Life 3.

For those too lazy there is a screen grab below.
You can clearly see Half Life 3 is the only game listed next to Valve. Could Half Life 3 really be coming out this year?
