When the new Meade 16" Lightbridge hits the stores, will it need a Paracorr to correct the image?

I have asked this question to myself and I think it just might. I'm no expert but from what I've read most scopes at f4.5 will need one.
Also, I understand that most Paracorrs will deliver a magnification effect of about X1.3. Is it the mag effect alone that helps correct the image or other processes? In other words, if I wanted to use a Barlow to achive a desired magnification, would I also need to use a Paracorr?
Thoughts.
