If Half Life fans are to follow the latest rumours surrounding Half Life 3, then they should know be aware that the highly anticipated is getting linked to a confirmation at the upcoming GDC event.
Like every other rumours, Half Life fans should take this latest buzz with a pinch of salt. This is because the chances for Half Life 3 to get announced at GDC are slim to none.
Half Life 3 is a massive title and GDC is too small of an event to host its confirmation. Also, there is the fact that GDC is mostly used to demonstrate new technologies.
Yes, Valve might have booked a slot at GDC but they will probably use their time to show-off their VR headset project. There is no way for them to announce Half Life 3 at GDC.
