Turns out that despite the rumors, EW says the likelihood of Summit Entertainment and Lionsgate merging are slim–

A source tells EW that those discussions actually occurred before Summit took the $37 million Twilight and turned it into a $340 million worldwide franchise. Now that they’ve got a real hit on their hands, Summit is going it alone for the time being, with the Dakota Fanning-starrer Push releasing on Friday, and New Moon, the studio’s Twilight sequel, scheduled for a Nov. 20 bow.

However, with the economic conditions being as they are, everyone in Hollywood is talking about ways to enhance their business strategically while simultaneously reducing overhead, so it’s certainly not out of the question that we’ll see some kind of changes taking place at various studios in coming months. We’ll just have to wait and see how it all shakes out.
