I wouldn't count on a T1 unless it got a crazy ammount of votes. T2 license covers Arnie's likeness within the film rights, T1 doesn't and will require the extra measures with his people again like with Dutch. As long as HT can get the T2 license, we're covered for Linda Hamilton, Robert Patrick and Arnold Schwarzenegger.
I'm game for a T1, but since I have nothing T1 in my collection, I'm more eager to properly finish off my T2 collection before starting a new film.
I'd like to see a biker costume T1 with Arnie likeness and a 1984 Reese if they do T1.
I'm hopeful they acquire the T2 license and maybe do a Cyberdyne/steel mill Sarah with the hair down, T2 clean so we can get a nice biker costume (those of us not lucky to have the Saturday Toys set), BD T-800 with phase 1 and 2 of Endo reveal heads, Biker T-1000, T-1000 with split head and eye hole head.
I do hope, any Arnie T-800's outside of a nudie one, best be on plastic bodies, Wolverine style is fine, but the Dutch body would be a shame and a waste, at no time as the Terminator do you see his build really so a plastic body is fine.
