Not really, while Netscape was still driving the Mozilla browser
development there was active work on ECMAScript edition 4 to be the
specification on which JavaScript 2.0 is based. But then Netscape
stopped the browser development and the guy working on the formal
specification of ECMAScript 4 and JavaScript was one of the many laid
off. And Microsoft had other plans for instance, instead of waiting for
ECMAScript edition 4 to become a specification they implemented
JScript.NET as the .NET based successor to the classic, COM based JScript.
As far as I understand from blogs and published slides work on
ECMAScript edition 4 has been resumed quite some time back and the aim
is to finish and publish the specification in 2007.
See <http://developer.mozilla.org/presentations/xtech2006/javascript/>
for further details, it even says
"JS2 based on ES4 in Q2 2007"

But even if Mozilla implements JavaScript 2 based on ECMAScript edition
4 in 2007 it remains to be seen whether and when other browsers
implement ECMAScript edition 4, at least if you hope to use JavaScript 2
on the web.

Actionscript 3.0 is supposedly based on ECMAScript Edition 4. They even
removed some features of Actionscript 2.0 (like private constructors)
specifically because that functionality is not allowed in the ECMAScript
Edition 4 specifications (at the time of this posting anyway).

Actionscript 1.0 and 2.0 were loosely based on the ECMAScript
specifications.
