I don't thing that they've announced anything new as of now. The 2X did just come out a few months ago though so if you really want to sit and wait for something better then go for it.

Personally, I work with a Replicator 2 and the new 2X at work. I think it would be worth it to get the 2X, but I really can't say for sure until I get a chance to try out Makerware 2.3 for a while.
