Many fans are curious why the gap? While it seems obvious to me that there are many reasons, my guesses would include:
-stretch out that money maker
-separate years equal separate awards shows and promotion trains
-allow time for dvd and other releases between films
There are many reasons this will work well, and I am honestly, pretty psyched at the time line, though I don't like the waiting now.
Here is a great explanation of why the November Releases and time lines may have been chosen.
Hit Fix explains:
“After releasing both “Twilight” and “The Twilight Saga: New Moon” in November of 2008 and 2009, Summit made the seemingly smart move of moving “The Twilight Saga: Eclipse” to a June 30, 2010 release date. This was because of both fervent interest from the franchise’s fanbase and the expectation that opening in the summer would allow for a larger gross due to the fact many teenagers would be out of school and able to see the film numerous times during the work week. Instead, “Eclipse” has grossed less than the previous chapter, “New Moon,” with only $288.1 million domestic and a total of $644.8 million worldwide so far. “New Moon” ended up with $296 million domestic and $709 million worldwide and it’s hard to see “Eclipse” matching that total as its grosses have slowed considerably. Considering “Eclipse” received universally better reviews than the previous two chapters and was the most action packed (i.e., male friendly) of the series this has to be something of a disappointment for Summit. Granted, there is no need to shed any tears as the studio and series creator Stephenie Meyer are still swimming in profits as the picture only cost $65 million.”
