They keep repeating the words "big screen version" in this article. There was never a plan to go to the big screen. If there were talks of it, then those are definitely rumors since JM has not mentioned his script as heading for "the big screen".

Brad Wright said that we will probably never see another Stargate movie hit the big screen. There are obviously some contractual issues involved. But those issues don't come into play when making DTV or TV movies.
