OK by me.  But if you keep the original name also, I'd suggest modifying it to
`switch-to-new-file-buffer'. It is a buffer intended for a new file; it is not
just a new buffer.

`open' is not really clearer here than `visit', but it is less specific.  It is
true that in Emacs we speak of "visiting" a file as reading its content into a
buffer. 

Whether `buffer-file-name' is nil at that moment, so the buffer is not actually
visiting a file yet, is less important than the purpose (use) of the command,
which is to create a buffer that will be associated with a new file.  The buffer
switched to is intended for visiting a file, even if that file does not yet
exist.

IMO, `Open' in a menu item is OK for both existing and new.  But you are correct
that in Emacs jargon the more correct term for an existing file would be
`Visit'.

I would propose (and have proposed ;-)) simply `New File' as the menu item.  It
is common nowadays to have a menu item `New' for creation when the object to be
created is clear, and `New Foo' to make clear that it creates a foo object.  (I
use `New File' and `New Directory' in my own code, `menu-bar+.el'.)

Whether we use `Visit' or `Open' for an existing whatever is not so important.
What is important is to clearly distinguish the case of creation (`New').
