Right. This is because `:results latex replace' is the default for latex src blocks and the leads to wrapping everything in a latex export block. 

The context inside that block is `export-block' - i.e. it is not a `greater-element' and cannot contain other elements.  AFAIK, there is not previewer for export blocks - latex or otherwise.

The context for an equation inside a greater-element is latex-fragment. And those can be rendered via `org-latex-preview'.

If you want to render equations for previewing, you could put them into a drawer that is not repeated in the export.

To make this work, you probably want something like this

#+begin_src org

  ,#+name: eqn1
  ,#+begin_src latex :exports none :results drawer 
  \(y = x\beta + \epsilon\)
  ,#+end_src

 
  Here is the equation for export:

  ,#+call: eqn1() :results latex

#+end_src

Evaluating the latex src block (C-c C-c) will create a `results' drawer line this:

#+RESULTS: eqn1
:results:
\(y = x\beta + \epsilon\)
:end:

but the `:exports none' will strip that out on export. The call line will create this on export:

#+RESULTS:
#+begin_export latex
\(y = x\beta + \epsilon\)
#+end_export


HTH,

Chuck
