Les Paul tuners

Do you mean the Min-ETune system?  It's frickin' amazing!  Go from 'I want to play' to 'I am playing' in the shortest time possible, almost instantly change the tuning to whatever you want (DADGAD, dropped D etc.) and makes string changing simplicity itself.  I have it fitted to my LP Studio 2013.  I was sceptical at first, but haven't looked back since getting the guitar.

How do they expect people to tune their guitars?? 

The issue with Min-Etune is that the gears would strip.
If that happens, you're SOL until you can replace the tuner/servo.
While it works, Min-Etune is very cool.  
Especially nice if you're playing live and having to move to/from drop-D (reason I had it).
 
One of the gears stripped on me... and I was done.
The locking Grover Tuners are excellent.  Put those back on... and just tune manually.
 

   Does anyone know if the stripped gear problem described above include the "G force" tuners as well as the "min E' tuners?  My impression (no facts) was that the G-force system was an improvement over the previous min E tuners.
The reference to the year 2015 would seem to lump the two system together.  Yes- I own a G-force Gibson guitar so if there is going to be a problem, I might just head it off.
   So far my guitar's tuner's have worked well.  It seemed to me that the biggest problem would be to train yourself or your roadies to change strings and work the robo machines.  They have a non-intuitive method of pushing little buttons to make things happen.  I have checked that if battery power fails, it is easy to tune manually so that argument against them is a straw dog.

The biggest reason that I got from the GC Manager at Central Express Way in Dallas, was that customers just didn't like the idea of paying $300+ more for the tuning system when they preferred to do that the old fashion way.  
 
I actually liked the LP Plus Less, the thinner bodied LP they experimented with in 2015.  They had them marked down from $1,899 to $1,200 the day I was in the store; around Christmas time.  They had just stripped the tuners from that guitar.  He told me to hold off for a while if I was interested in the guitar, because they would be dropping them even more dramatically than that.  He said, "know one wants them."

I have locking Tuners on all my guitars...and always will...

That is all...

Me too...
String changes are super quick/easy.
Will have them even with FR style trems

I was wondering why so many UK retailers have been offering huge discounts - as much as 40%+ off - on various models from the 2015 Gibson range.

Personally much of the recent tweaks and changes to Gibson models have pretty much meant they're not very attractive to me. Nothing to do with self-tuning, but character-changing stuff like SGs with fat necks and big frets, Firebirds with over-powerful pickups and the sheer ugliness of much of the newer models in the current ES semi range. There seems to be an attitude of constant chop and change and a ridiculously confusing number of variations on the same design spread over a huge price range while a "like for like" replacement of a guitar a few years old simply isn't possible because they're not made like that any more.

If something happened to my 1990s P100 equipped ES135 for example, there's nothing in the current Gibson range I'd consider as a replacement. Come to that I can't even replace the pickups with OEM ones.

To be fair, Fender suffer from a similar problem as do Martin and Taylor.

   I agree that locking tuners are great.  It amazes me to see so many guitars selling for north of $1000 without them.  The manufactures are themselves "out of tune" with their market.

Necks, or at least the feel for me, on Gibson's feel like a "2X4".  I was in Nashville several years ago, when Gibson had the store and production facility in the Opry Mills shopping center.  They had a room with a bunch of LP's on a special sale.  Most of them had wild paint jobs and probably didn't sell and why they were selling them at the discounted price.  All of them I tried sounded great but seemed like the "2X4" neck, to me. 
 
In Gibson's defense I've played Chet Atkins Gretsch's for a long time (had a new 1961 PX6120) and also have a Fender Telecaster.

Les Paul 60's neck feels pretty good to me.
Don't care for the 50's... which is more "baseball bat"

I like those.  I like the PRS wide fat necks but that's an expensive neck outside the SE line.
