Because it is replacing the Titan workhorse.

This also leave rooms for NVidia to make a 3080ti with more memory on it and a cut down 3090 core.

I've seen some users predicting a TI or super in January or February however, I believe that may be wrong unless I missed a article around here.
The only way I see that happening is if AMD pushes them to do so. Otherwise, I would be surprised if any other cards is pushed out within the next 9 months to a year.

 Possible to make a 12GB variant for lower price?  and for those people that want to do 8K res buy the 24GB variant.  
i do not need 24GB only want the extra performance of 3090.

It's purely because of chip binning.  They only have enough good "full" GA102 chips for a limited number of consumer and workstation cards, so they decided to put out a 24GB version with the full chip and high price to maximize profit and limit demand. They evidently had a ton of chips they could offer with a 10/12th's cut down, hence the 3080.
 
At some point they'll have enough good chips / better fab yields to where they can release a 3080 Ti/Super card with a 11/12th cut down or full chip and 11 or 12 GB memory.

Then nobody will want to pay for a 3090 24gb. They want the consumer who was dead set on paying $700 for a card to think long and hard about paying double.

If all the predictions are correct(they could be wrong) then AMD's flagship RDNA 2 card will slot right between the 3080 and 3090. I am sure Nvidia is ready to have an answer for it.  If AMD has a $999 16GB card that is slightly faster than a 3080 and Nvidia releases a 3080TI for the same price with equal performance which one would you buy...... Nvidia knows what they are doing and are just waiting to show all their cards...literally.

GDDR6X is a Micron/Nvidia exclusive and rumor has it there will be no HBM on the AMD card. That leaves AMD with GDDR6. I predict Big Navi will be slightly faster than a 2080ti.

This is a mature process. It is 2 years old and has been used numerous times.

They didn't market it towards gamers, they marketed it towards the Titan market(rendering, photo/movie editing, ML, etc). The 3080 was marketed as the flagship for gaming. If you halved the VRAM it would then more widely appeal to gamers too while still having the huge original target market that needs 24GB+ of VRAM. Not to mention if someone actually wants to game in 8k, 12GB most likely isn't enough.

NVidia begs to differ as plenty of people want the 3090 with exactly what it comes with. They don’t want to wait 9-12 months for another card to release.

I think we are saying the same thing. Right now people who want a 3080 are strongly considering the 24gb 3090. However if a 12gb or 16gb 3090 is released alongside the 24gb model, nobody will want the 24gb model with some exceptions.

I think we are on the same page. Next year when NVidia releases their next iteration of Ampere, people are going to be furious because they spent the money on the 3090, but that is 100% on them. NVidia plays the game the best way that suits NVidia’s marketing and gains.

Maybe, but they always want to improve yields.

Because they will? They first want to get all the people who will spend whatever money on a high end card. Then in ~4 months they will release a 3080ti probably which will just be a 3090 with 12GB for $1199 or something. Also I would not be surprised to see a 3080super with 20GB vram.

You may be correct. AMD does like HBM though and I could definitely see them using it again. They had 16GB of HBM on the old Radeon 7 and that still has more memory bandwidth than an RTX 3090 does now..... just the Vega architecture sucks. We will see though, AMD's hardware is usually pretty good..... it's their drivers that usually hold them back. Even if they do go HBM I don't seem them competing with the RTX 3090 though.... its a beast.

I'm guessing a 3080ti with 16gb will come out down the line, likely on a 352 bit bus.

352 bit bus would be 11/22. You need 256 for 16GB.

3080ti coming jan-may 2021 with 12/16/or20gb ram and price between 899-1299 and fits between 80/90. Yup!

Sounds reasonable it would be some combination thereof. Unfortunately I don't want to wait until when a Ti may or may not come due to wanting to get something before Cyberpunk :D

Please google search "Double Face Palm"...this should give you your answer.
