I can almost guarantee you guys the hood is the same. There is no way they would re-tool for a new hood that was close but ever so slightly different and the difference you're seeing in the picture is so small that it could be light, shading, angle of the photo, etc. In fact, it's not "could be" so much as "is". When it all shakes out I'm willing to throw money down on the fact that the old hood will be identical to the new. 95% of the aesthetic retrofit is going to be the bumper cover. The only real unknowns are the small parts behind the floating logo. We don't know if that's part of the bumper cover, if it's it's own piece, etc.
But I'm willing to bet that for us pre-AP guys we're going to be able to swap bumper covers, add in the trim piece for the grill and call it a day.
The potentially complicated bit here is going to be the headlights. I vaguely remember someone taking them apart and stating that the controllers were inside. That's great news. If they are CAN controlled and the new lights also have internal controllers than in a best case scenario you might be able to simply plug them in and tell the firmware that the car now has LED lights. Easy peasy.
I've seen both side by side and the hoods are different. I suspect that the hood shape change is one of the reasons for the increased range.
