As a former movie theater & home video store manager, the old "lists" of release dates were always 180 days (6 months). The first movie to break that tradition was BATMAN in 1989 when it was shortened from a June release to the November release on VHS.
These days, if a movie is a big hit, the studios tend to withhold the title and squeeze as much box office as possible (see WALL*E and almost any moderate hit from PARAMOUNT). Paramount withholds their titles longer than most studios for home video/cable TV releases. Warner Brothers tends to shorten their releases to cash in. Two schools of thought as to which one is more profitable.
A newer promotional technique is that if a movie bombs or disappoints at the box office, the studios release to DVD faster to capitalize on the TV and print ads from the theatrical release to translate to "branding" on the home video release. SERENITY was a flop for Universal so they released it to video right away to justify they print ad and TV campaigns.
