I don't have an opinion for series 5 and 6, but series 4 will most likely be released late November, say like 21st of November in US. And it will be about 2 weeks after international, since NECA likes to make me wish I was American or atleast lived there.
Same for the two pack.
By the way, I just watched Predator 2 and well it looks like he shot the spear from his gauntlet.
And I kinda just realised this too... The helmet and spear should still be intact. The mask is in the butchers on the ground floor with the 'ground' beef.
and the spear is at the bottom of the alley way along with harrigans gun.
ANYWAY back on topic! Super excited! I will most definitely have my girlfriend ship them over from the states for me. ^___^
