Customizing org-e-beamer-environments-extra should do the trick.  I was
experimenting using the *scratch* buffer, so the following are temporary
settings, cribbed from those experiments: restart emacs and they
disappear.

Something like the following perhaps (very lightly tested - nb: I really
haven't played with the new exporter very much at all):

--8<---------------cut here---------------start------------->8---
(setq blockenv '("block" "b" "\\begin{itemize}\\item %h" "\\end{itemize}"))
(add-to-list 'org-e-beamer-environments-extra blockenv t)
--8<---------------cut here---------------end--------------->8---

I added a beamer entry to org-e-latex-classes as indicated in

  http://thread.gmane.org/gmane.emacs.orgmode/61497/focus=61536

by just copying the article entry and modifying it slightly (again, I
have no idea if the sectioning stuff matters or not, and whether it leads
to problems - improvements/corrections would be welcome):

--8<---------------cut here---------------start------------->8---
(setq beamerclass '("beamer" "\\documentclass[11pt]{beamer}"
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
  ("\\paragraph{%s}" . "\\paragraph*{%s}")
  ("\\subparagraph{%s}" . "\\subparagraph*{%s}")))

(add-to-list 'org-e-latex-classes beamerclass t)
--8<---------------cut here---------------end--------------->8---

That's enough to export your ECM I think - no guarantees for
anything more complicated.
