Now.....they are doing a (M)TV show, they had castings and all...I don't know when it's coming but I guess this year. If it's a "success" I can see them doing another movie.
But if there won't be one I am happy too. I loved the 4th and wouldn't want to miss it.
To be honest, as much as I love the franchise, I'm tired of Kevin even speaking about Scream in terms of playing the 'victim.' Granted, he's very talented and Scream 1/2 were great and the installments without much of his involvement suffered.
However, he was basically too busy to have anything to do with Scream 3. And with Scream 4, he was constantly behind with the writing to causing others to step in, so honestly, I don't much blame the studio.
