Judging from announcements made Monday at the Consumer Electronics Show in Las Vegas, a veritable flood of movies will be released this year on Sony's Blu-ray DVD format. Sony's own corporate sibling, Sony Films, said that it plans to release up to 100 movie titles this year. Warner Bros. said it is likely to reduce a similar number of films, while the smaller Lionsgate Studios said that it plans to offer about 40-50 titles.
