I think Nvidia somewhat rushed into producing the 4000 series although their production cycle is once every year for the main GPU-s.Seeing the popularity of both 2000 and 3000 series still it is only natural for them to delay even further the 4000 series.

Gamers may complain but I think gamers should not complain,the 3090 24 GB is capable of running anything paired with a good processor.For the miners,we would be happy to see the soonest the 4000 series hitting the market which would cause another drop in price in the 2000 and 3000 series,of course if 4000 perform well but I think that will be highly likely.
