Hi overhearyou,
A select group of professional FCP editors such as Walter Murch were invited to Apple in February and shown the next version of Final Cut Pro. Thought they had to sign NDAs it has been called "dramatic and ambitious" and the biggest overhaul since the original. Steve Jobs has responded a couple of times to emails from people fretting that they were jettisoning the Pro Apps telling them it wasn't true and, in his words, to "buckle up". If it isn't realised around NAB (which is just around the corner) it will be very soon. Due to it being a dramatic overhaul, I would wait for the new version just in case it lands just outside the free upgrade grace period. I would also wait because from the sounds of it, with a huge overhaul, there will be new learning curves so it wouldn't make sense to learn the app twice.
There are a lot of naysayers with regards to FCP and its true it has fallen behind somewhat. This is because it has had to be completely rewritten from the ground up to take advantage of 64bit technology. It has a huge place in the professional marketplace and with people like Murch, The Coen Brothers, David Fincher, etc. being active users, from a marketing standpoint alone for the Apple brand, they'd be shooting themselves in the foot to let it slide.
Sit on your money, lock yourself in a cupboard with your mac, pull up the apple store site on your browser and keep hitting refresh until it appears ;-)
