I don't like it. Yes it looks good in this slide, but there are still a number of unknowns which won't be revealed until they're in the hands of the reviewers.
Smaller L1 cache for larger L3 cache, which is going to result in increased latency, though AMD states the performance improvements will offset this.
Up to 15% higher IPC depending on workload, so we won't know what the typical IPC improvement will be. It's entirely possible average IPC gain will be half that, which will put Zen 2 still behind Intel in terms of performance per clock, and make upgrading from Zen+ or even Zen a questionable decision.
It's known AMD is stripping official PCIe 4.0 support from 300 and 400 series boards, so even the "PCIe 3.7 or so speeds", as article have stated that it wouldn't be true 4.0 due to technical issues, aren't going to be possible even though those speeds would eliminate a bottleneck of the fastest GPU currently, the RTX 2080 Ti which is bottlenecked by PCIe 3.0 x8.
And let's not forget, Lisa Su even stated X570 motherboards "will be expensive", and since this is the last Socket AM4 CPU range, unless AMD decides to delay AM5 until 2021 though much of that decision will no doubt be related to DDR5 and PCIe 5.0, any future upgrade path will result in a new motherboard required.
