Yes. It's been announced at E3 that NECA, makers of fine action figures (increasingly these days based on games), have picked up a license from the Half-Life creators "to produce consumer products based on Valve's much-acclaimed games".
That will mean action figures at an absolute minimum, but hopefully also given the wording things like replica props and weapons too.
Like, say, crowbars. And Portal guns. If you're wondering which franchises are included in the deal, it includes all of Valve's series, meaning it's not just Half-Life but Portal, Left 4 Dead and Team Fortress 2 as well.
Be still, my beating heart.
