It's still within the extreme UV range. After 7nm it really gets complicated, but even 5nm is probably possible.

Today we are drawing 14nm features with 193nm light, and contemplating continuing with it for 10nm.

13.5nm EUV will cope with 5nm.

I'm skeptical but I won't say it's not possible. I'm also skeptical that quantum effects won't make lithography this small impossible. Silicon atoms are 0.2nm wide. 5nm Lithography is cutting circuits just 25 atoms wide. That's frankly incredible but I have to wonder what bad quantum effects they are going to run into at that level. They already have trouble with quantum tunneling and it's only going to get worse as things get smaller.
