After all these years I've learnt to take every one of these launches with a grain of salt (A mountain sized grain of salt)
But as Jules Urbach said, there is potential but since it's brand new tech they need to figure out how to make it work.
Right now all the the new features that have been announced for 2018.1 are a lot more exciting and given the current pace of development at Otoy, I think we might actually see a 2018.1 XB1 in September.
I'm really curious to see what this Vectron stuff is all about.

Well, this is what I've gathered so far from different sources.
New Cards WILL BE FASTER, as they offer more cuda cores (RTX 2080 ti vs GTX 1080 ti). But in future development of Octane we will (overtime) have those RTX cards have a better performance over the GTX. Which means, there's no need to rush and switch all of your 1080 for 2080s in the next month. I'd give it 6 months to a year before we can see a real leap of performance when using all parts of the chip to render and not just the coda cores. The new Tensors cores are in theory far more powerful than the Cuda cores.
Conclusion: If you have 1080 Ti, stick with it/them for another year. If you are in need of new hardware that will last you at least a couple of years, then get an RTX card.
I am thinking 2x RTX 2070 maybe just as good or better than a 1x RTX 2080ti and roughly around the same price.
The Quadro is probably the best of them all, but not everyone can afford a Quadro card. I am sure they'll come up with Titan T in the future and those will dominate over the 2080Ti which may mean that those will drop in price fairly quickly IMO. I bet the MSRP on the RTX2080ti will be under $800 early next year.
I would love to hear from OTOY about all of this soon, in case they want to enlighten us. Also, benchamarks, they can't be here soon enough.

I'm so hyped for the performance increase! I hope OTOY keeps us updated.
For now I'm just glad I didn't waste money on all those 1080 Tis I got

I think, it's safe to think that 2080ti has today the same performance as the titan V... which is already VERYGOOD.
...after that... we will have to wait some months for more improvement.

Probably even better at a lower cost, but it wouldn't be twice as good or so until new software updates to make use of the gigarays.

Well, if that 5x-8x speed increase is not happening anytime soon - in other words in 2018, then hard pass on these cards i guess, cause its rumored next year we may see already new generation built on 7nm process - that might apparently be the reason why we see 2080 ti now already alongside 2080; and not usual stacked release x80 card first; x80ti in 9 months..
Too bad, cause i kinda wanted to indulge myself with some new shiny hw

i think if octane will use these rt cores with their brigade we will see 6-8 times improvement. There is even a video where otoy says about it

I don’t think any of the 5-8x speed improvements are going to happen for at least another 8 months. Or Until otoy has a stable version of octane 2019 which uses their new RNDR SDK.
That video is a promo video by NVIDIA. Everything Jules Urbach says in that is true but it doesn’t give the full picture. Watch the other video to get the full picture. He says clearly that they need to work on it and it will take time . Also there are issues that NVIDIA needs to solve at their end.
Of course, NVIDIA can’t make a promo video saying ,
“Introducing Brand new RTX technology. Get 5-8x speed up in render times. Just wait till your software developers implement this. Oh, it might take 6-8 months to do that. Maybe more. But then it will be awesome. We think, maybe. Pre-orders open now”

If i understood that correctly with my limited english knowledge, he said RTX is implemented via Optix. Vulkan or DirectX....they have Octane built around Optix already (?), but somehow that stuff is not finished on Nvidia side - as you say. Vulkan version on other hand, they are working on it now, but sadly he did not give any timeline, when we can expect it to be released.
If it ends up 6-8 months, as you suggest, thats quite sad - but what can we do. Obviously Nvidia is not going to say the software for their cards they want to preorder now, is going to come out next year - that is why we are discussing this on OTOY forums, rather than Nvidia´s

Is Vulkan kernel a new true kernel you will have in Octane or just an integration of an Nvidia technology ???
