Ah, don't misunderstand, the latter part of my post was pure speculation. Mostly, I was just trying to point out the difference between the TH and TG brands, which can be confusing to a lot of people.
To address your points though, the article does make a few brief comparisons to the 2012 model (though it doesn't get very in-depth), and the loss of the ability to upgrade certain components yourself is also stated. The focus seems to just be more towards comparisons to current similar/related products you can choose from as opposed to the older models.
