What gave me pause when I read the website page on the new changes and watched the videos was the thinner finish. Over time the finish on all my Taylors thins out as the solvent gases out and one can see the washboard effect as the soft part of the grain shrinks in. Having a thinner finish no doubt gives a head start on the guitar opening up, but at the expense of getting a new dent or mark on the finish every time I pick it up.
The new Expression 2 pickup gives me pause as well because it looks like the saddle is resting on the pickup insert that gets wedged into the underside of the saddle. Seems like there's gonna be some transmission loss of energy there. I applaud Taylor for trying to improve it's pickup system cause I have the newest system and hate it. It seems like the new string gauges are a way to even out the piezo response from the new system, perhaps. If I never use the pickup I hope I'll get just a good a sound with my customary custom light Elixars.
I also miss the abalone rosette and the rosewood pickguard doesn't appeal to me. I guess I'm an old dyed in the wool stick in the mud, but I'm giving this one a frowney face.

That is until I actually pick one up and play it and it changes my mind.
