You're in the wrong forum. If you had read a little more carefully, you'd see this is the Mac Pro forum, not the MacBook Pro forum.
That said, my feeling with laptops is always that the current model is always good enough, because the current model, even the day after a new one comes out, is always slower than what you can get with a desktop. As such, performance doesn't matter so much, so specs don't matter. If specs did matter that much to you, you'd get a desktop.
Obviously desktops aren't as mobile, and people get laptops for mobility, so choose a laptop based on mobility. The two times I've gotten Apple laptops, I've always checked them out first in a store to see how heavy they feel, how good the keyboard and trackpad are, etc. If it's acceptable, I'll get one. Last time, a new model came out just a couple months later. I didn't regret my purchase.
I have an older MacBook Pro than the current model, and for what I need it to do, it works great. I'm sure the current model is even greater. Go to a store, try one out, figure out what size is best for you. Don't worry about the specs of the next one coming out next week, next month, or next year. If specs were important to you, you'd be getting a desktop.
For Mac Pros, on the other hand, specs mean everything.
