We've been hearing rumors about a GeForce RTX 2060 since at least August, with screen captures of a reported mid-range Pascal card (then assumed to be "GTX" 2060) – seemingly with GTX 1080 levels of performance – surfacing at that time.
Then in November there was the reported Final Fantasy XV benchmark leak, showing performance a little below a GTX 1070 with the game running at 3840×2160 (high quality preset) – but this was possibly the mobile skew according to leaker APISAK on Twitter.
A week or so ago we saw an image of a Gigabyte card from VideoCardz.com which the site said was the RTX 2060:

"Our sources at Gigabyte have confirmed GeForce RTX 2060 graphics card launching soon. The card features TU106 GPU with 1920 CUDA cores and 6GB of GDDR6 memory. The model pictured below is factory-overclocked, but the exact clock remains unconfirmed." (Source: VideoCardz)
It seems fair to assume that a launch is imminent, with reports of a potential announcement the second week of January which may or may not coincide with CES 2019. As to final specs and pricing? Let the speculation commence!
