There are some many clues that indicates that the movie is a fake that I don't even know where to start...
First of all the so-called movie is supposed to be released on June 6 2010. Nice and all, but that would mean that the Japanese release date is already known. But the release date of the 10th movie in the US isn't even known.
Second, the name: James Ketchum. The 10th movie dub names aren't even known yet, but for some reason the dub names of the 11th movie?
Third, the person who wrote this is most likely someone who thinks that Pokemon is made and writen in the US. Enter the search query
"Rick Shawn" pokemon in Google. For someone who supposed to be the representative of the Pokemon franchise, he sure is unknown. Besides, the producer should be someone from Japanese, because all Pokemon movies are being made in Japan and first to be released there. This Rick Shawn is talking like he is the one who is making the movie. FYI director Yuyama Kunihiko is the one who makes Pokemon movies.
Fourth, "self programmed"? Deoxys is a (space) virus, not a machine or computer program.
Nintendo and Game Freak are coming back and are going to make 3 video games for this movie
FYI: games are being made -> the anime is based upon those games -> movies are made as addition to the anime. Not the other way arround.
Pokemon & Co? If it was saying Pokemon USA or Shogakukan Production or OLM it would be more realistic
-----------------------------------------------------------------------
Bottom line: I highly doubt it is real. New Pokemon movies are usually announced somewhere in December or Januari in Japan. The 10th movies hasn't even been released yet which makes the whole thing even more fishy.
Ofcourse, if someone can contradict me by providing an official source, please do so.
