No chance. AMD might though.
5060 will be 8GB & 5070 will be 12GB, confirmed by multiple leaks. There are ignorant people who bought 4060 & 4060Ti at it's bad prices for gaming, so there will definitely be people who will buy the 8GB 5060 at $300. IMO DLSS & RT are not worth it at even the performance level of 4060Ti now considering the increased requirements making 4060Ti 8GB a 1080p card (upscaling from resolution lower than 1080p might be good for handhelds or even laptop, but not for 24" monitors).
