Will the new Haswell Macbook Pro be worth the wait?

Will the new Haswell Macbook Pros be worth the wait for the non retina model (will there even be a non retina model) I recently got a 13 Macbook pro 2012 model 2.9ghz i7 8gb ram with a 750gb HD, But I haven't opened it yet because Im afraid I will regret it if the new one comes out soon (Sept. or Oct. events). Also if I keep this one I want to possible replace the HD with a SSD first thing if it doesn't void my applecare. Sorry for the long post. Your help is appreciated!
