 Status
 =========
 
-xxx a status slide could fit here
-
+* still rough edges that need polishing
+* still missing a few important extension modules
+* right now, useful parts: special languag features; RPython for high-perf
+
+Performance
+=============
+
+Current interpreter performance is not bad, but lower than CPython:

-.. (empty transition slide to say "in this talk we're mainly focusing on...")
+* our trump card to run plain Python programs fast
