Ehhhh, not really, but the release seems a bit different this time around. The 1080 Founders Edition and 1080 Ti FE cards both debuted at $700 USD. (The 1080 Ti was released nearly a year later.) This puts it closer to the now released 2080 FE, which is $800 USD.
The 2080 Ti FE, however, is in a league closer to the Titan X/Xp, which were at $1,200. Also they're releasing the highest-end Ti edition at the same time as the ordinary version, which is a first for Nvidia, I think? (The Titan Xp was also launched after, not concurrently, with the 10xx series...) I think the concurrent launch of the 2080 Ti with the ordinary variant means they're positioning it more like an alternative to the Xp, while the non-Ti variants are closer to the ordinary gaming cards you'd normally get. In other words, for people willing to blow their price/perf budget a bit more.
For DL workloads the 1080 Ti is very cost effective (vs the Xp), so it remains to be seen which variant will have the better bang/buck ratio for those uses. I suspect the fact these include Tensor Cores at their given price point will probably be a major selling point regardless of the exact model choice, especially among hobbyist DL users. The RTX line will almost certainly be better in terms of price/perf for local DL work, no matter the bloated margins vs older series.
They may also be keeping prices a bit inflated, besides margins, so they can keep selling older stock and pushing it out. The 9xx series, as you said, continued to sell for a while after 10xx was released. I expect the same will be true this time around, too, especially with prices being so high.
