No idea - but - IMHO nobody is going to rush the change of the official version. You should bear in mind that this change will exclude all that still use NT4 or Windows9x. & AFAIK the change to 1.9 creates much more work than some previous GRE changes.
Until then You can use Gecko's newest ECMAScript test engines with all K-meleon test versions - that can use the 1.9 engines.

You can use the GRE versions mentioned or SeaMonkeys with 1.9.1 or so engine.
