It depends what they release. I have a strong feeling that they are doing a 12nm large die for a new xx80ti and titan. Then everything else is going to be a rebrand of existing chips(the old 1080ti die is the new xx80, the old 1080 die is the new 1070 and 1060 etc). If that's true....it makes perfect sense to lead with the new xx80ti.
With the crash of crypto, the supposed overstock of pascal dies, as well as 7nm not being ready yet.....it would make a whole lot of sense to make 1(maybe 2) new die on 12nm(which is really just 16nm with a larger reticle limit) for the high end, and then rebrand everything else for the other segments.
I am not saying this is what they are going to do, just what i think they will do.
Some recent leaks have indicated that the 2070 and above will use RTX branding, while 2060 and below may continue to use GTX branding. If that turns out to be true, then it implies that at least the RTX cards will likely be new designs incorporating raytracing hardware (hence the RTX). And if the rumors of a GTX 2060 with 5GB of GDDR6 are to be believed, then that also won't be a simple rebrand, even if it were to use a Pascal-based chip. I also kind of doubt that they would rebrand the 1060 as a 2050, as they likely want those cards to be compatible with systems without additional power connectors, and available in low-profile options.
The RTX Titan and 2080 Ti might be based around one new chip, and the RTX 2080 and 2070 around another. The 2060, 2050, and 2030 could each be based on new chips as well, but it will likely take months for each of those to come out, giving them time to ramp up production and sell off existing cards.

After 11, they could have moved on to 12 and so on. Now, going from 20 to 21 will seem so lame. So by that measure, I guess they will move on to 30 after 20? Sheesh!
People in marketing are often idiots!
By changing the first number, it keeps the product names visually distinct, whereas if they went with 1180, 1280, 1380, that "1" is just sort of hanging out there, making them look too similar. Nvidia has always changed the first number of their product names from one generation to the next, at least since they started primarily using numbers to classify them, so it makes some sense that the trend would continue.
Also, people tend to have certain psychological responses to various numbers, and the number itself can make a potential customer feel differently about a product. Some numbers are simply more marketable for a given product than others, which can explain why certain numbers are sometimes skipped.
