Is Eddie Brock/Venom Dead?

Venon /Eddie Brock is a fictional character who is the enemy of Spider man. He was the result of symbiosis between an extraterrestrial symbiote and a human host- Eddie Brock. In the recent movie Spider man 3, Spider man manages to trap Venom in a circle of pipes and rings them at a frequency that subdues the symbiote and as a result the symbiote detaches itself from Brock. Spiderman tries to save Brock but Brock dives back. At the end of the movie, when the smoke clears up there is no sign of the symbiote or Eddie Brock. It remains unclear whether he is dead or will come again in the next movie.
