Something that I've noticed is that while a lot of unofficial news sources and websites are referring to Indy4 as the final installment in the series, the official press releases and the latest info we've got only refer to it as the ''next installment'' with no mention of it being the last. Is it possible that we might be getting a 5th and maybe even a 6th Indy? Back in the 1980's, George Lucas claimed to have signed a contract for 4 sequels to ''Raiders of the Lost Ark.'' Now, counting ''Temple'' as a sequel, that still leaves two sequels. Not counting ''Temple'' since it was a prequel, it leaves three films to be made. Perhaps a new trilogy? Could this possibly be happening in the future? Perhaps Indy 4 and 5 will be shot back to back ala the Lord of the Rings trilogy.
