Does Venom bring Carnage into the mix?

On the back of the news about the Venom movie, Amazing Spiderman 361, the first appearance of Carnage is starting to get some heat in the secondary market place. This comic can be purchased on the bay for a reasonable price (depending on the condition of course). But is that about to change with Sony announcing the Venom film , could Carnage be seen as Venom's antagonist , especially as rumour has it that Spiderman won't be featured.

How do Sony Play this ? Is ASM 361 worth picking up while its cheap?
