Starting from the day after tomorrow it is to stand already in various variations in the stores - and allegedly also with clearly better availability than the larger sisters RTX 3080 and RTX3090...
The speech is of the coming RTX3070. This is based on a smaller ampere-chip (GA104-300), which hopefully achieves a better yield rate in contrast to the larger model (GA102-200/300). Nvidia would certainly like to see it, because the RTX3070 should become an exciting option for video editing for many users.
It offers "only" a 256-bit wide memory interface with 560 MB/s, but its performance should be approximately on the level of the top model of the last 2 years (RTX2080 Ti). But at half the price (approx. 500 Euro/Dollar) vs (1.000 Dollar/1200 Euro). The power consumption of the card is indicated up-to-date with approx. 220W, which is not much less than the TGB of a RTX2080Ti (250W).
However, the launch is overshadowed by AMD, whose RX6X00 series will be presented tomorrow. Allegedly AMD will be able to compete with Nvidia on equal terms for a long time.
And also the company-own rumors in the run-up to the RTX3070 speak for the fact that one should perhaps still wait a little bit with the purchase of a new graphic card. Because the usual rumor sides have up-to-date not only one coming 
RTX3060Ti on the radar.
Also a RTX3070Ti became already sighted. And a possible RTX3080 is to stand also already in the pipeline.
To all this Nvidia could give its current models relatively promptly additionally more memory, if AMD should show up tomorrow too abundantly. So better leave your wallet a little bit longer - maybe the fog has already cleared a bit by Black Friday.
