The thing will do fine on trails either way. What happens with terrain response may be odd to us, but people have been enjoying those features on pickups and other SUVs since they aped Land Rover's technology. Electronic lockers are fine. I'd almost rather have one than an air locker, honestly.
If the vehicle will function without those systems, there's not really an issue; rather like a DII without traction control. It's a wonderful system when it works, but when it doesn't you're still not stuck on the side of the road, and it's still a monster in the right hands.
It's funny how Land Rover is constantly picked on, when they're the origin of so much crazy technology and styling. They're now leading trends from styling right down to performance. That's an interesting development.
For me, the Defender is going to come down to what layouts they offer eventually. I'm sure it will be fine for most of what I'd do with it, but it's got some competition with the Jeep Gladiator (so long as it doesn't drive like anything Jeep has now), the Ridgeline, and AEV stuff off the rack, for me. I'm still not sure what the hell I want.
Land Rover could be producing a good middle ground here, but may reveal something that's actually got the brawn to back up the brains. Looks like we're finally going to find out soon.
Cheers,
