First 7nm chips are already released, though they are GPUs; Radeon VII, Radeon Instinct Mi50 and MI60. CPU is sampling right now which means release is just a couple months away - I expect a June release, which would still beat Intel by over half a year minimum.
I can definitely wait until June.
I'm sure the RTX 2060 paired with my 4670K will give me a good enough experience in the meantime, so I'm not really losing out on much. 5 months ain't long to wait to un-clutter my media centre. It looks a bit comical at the moment as I have an almost bezel-less beautiful OLED TV with my gargantuan PC sat directly behind it (you see the profile when you enter the room) - the pinnacle of exquisite, sleek consumer electronic design combined with a huge chunky monolith... a bit like wearing a Hugo Boss suit with a pair of wellies :)
