The two editions will likely be very similar. A friend of mine is expected to receive the 12th one of these days and I will update you once I've taken a look at it.
Here is what I already know:
The OG12 has 840 pages (https://tinyurl.com/c8txjw) while the current OG11 has 832 pages.
There are about new 300 questions in the OG12. Since it is essentially the same size as the OG11, I would conclude that most of the questions will be the same (the OG 11 has 907 questions, so perhaps 1/3 of them have been replaced)
Argument for getting the OG12 right away
You will likely get a greater number of difficult questions because that has been the GMAT trend over the past couple of years (average GMAT score has gone from 530 to closer to 540 I think).
You'll get to show off your new book to the OG11 crew and feel good about yourself.
hmm... honestly I don't know why else you would get it. There hasn't been any major change in the content tested.
Argument against getting the OG12 right away
The OG11 has been the standard of all GMAT prep programs for 5 years now; by keeping the OG11, you can make better use of the other materials that have been designed to work with it. I'm thinking in particular of the MGMAT guides that assign homework in the OG11 and of The Official Guide Companion from gmatfix; If you use these or similar guides to learn the content, it only makes sense to keep the OG11 so you will know which specific questions you should work on to practice a given topic.
If you switch to the OG12 right away, you may learn the content elsewhere (the OG was never designed to teach, but only to offer practice) but once you've finished the lesson on, say "Inequalities", how will you quickly determine which 60 questions out of the 900 would allow you to practice and perfect the lesson? If you have The Official Guide Companion from gmatfix or a strategy guide from ManhattanGMAT, you would just go to the reference section and identify where to go in the OG11.
Basically, think of the OG12 as Windows Vista when it first came out. It was new and shiny, but the software around was mostly designed to work with Windows XP, so although the Vista users got a big boost of pride, they just couldn't do a lot of things that XP users could do. Vista has become better as the market has adapted.

Well, I've been trying both 11th and 12th edition of OG. I'm done with 80% of 11th and now working with 12th. The reason I choose 12th, thinking of getting more diversity and new problems. It seems so far that RC and CR has lot new addition of questions, SC seems to be repeating few questions. (Haven't seen a Quant section yet)
It would be really an early stage to affirm anything, but would say that, 12th edition is worth to have when you haven't really worked on 11th, its a transition book and not a whole new edition with all new questions.
Rest all informations remains same including preface and introduction before each sections. It is like when syllabus changes in school and few things are been updated. So, to sum it up, if you stick with 11th there is no harm. Hope it helps !!

Manhattan GMAT did a breakdown of the actual questions that are new in the 12th edition.
The newer quant and verbal are now available, if not on the site, to those in the biz.
Working with this material, whether 11th or 12th, supplemental editions, or not, are the best to work with...real, retired questions, written in the test-writers voice...
can't go wrong there!

As follows is what I got from GMATFix.com :-
About 2/3 of The Official Guide 12th edition is taken from the 11th edition. The diagnostic tests at the beginning of the two books are identical. Most of the problem solving questions overlap; however the OG 12 has a lot of new data sufficiency questions. Perhaps the GMAT is moving towards increasing the ratio of data sufficiency to problem solving questions.
The following link should be quite useful.
It is by far the most comprehensive comparison that I have found on the internet.
https://www.manhattangmat.com/gmat-official-guides.cfm
This is another good link.
https://www.manhattangmat.com/official-guide-12.cfm
Read both the links to get a comprehensive idea of the differences.
