Sam Raimi has not made any statements about a Director's Cut although Columbia have been known to release extended director's cuts on DVD for other titles in the past including Spider-Man 2.1. If a Director's Cut DVD is ever made of this film it is likely to be called Spider-Man 3.1 and be released to coincide with the threatrical release of Spider-Man 4 (just like Spider-Man 2.1 came out on DVD to coincide with the cinema release of Spider-man 3).

It is widely believed that the Symbiote that Connors has will eventually bond with the yet to be introduced character of Cletus Cassidy to form Carnage.

Note that the above Post says Eddie Brock Jr is dead. Eddie Brock Sr could very well become the next Venom. though he hasn't been introduced as a character yet, only time can truly tell.
