The New MacBook Pro

The new 15” Mac Book Pro seems to have been quietly released with force touch as one of its most interesting features. I’m saying quietly because this was done not at any special event or even waiting for WWDC. However can anyone please list out the new features in this one? Overall, is it a major upgrade?

I have a mid 2012 retina MBP. Should I upgrade?

Lastly when the MacBook came out a couple of months ago everyone was raving about (among other things) the new keyboard.

Do we have a similar keyboard on the new MBP?

Thanks

Tony
