The new MakerBot Replicator is meant to replace the earlier Replicator 2 model. No, it's not called the Replicator 3 -- it's just the Replicator. It has a 100-micron print resolution and is optimized for PLA. It's on sale now for $2,899.
MakerBot is also giving us new apps. First, the MakerBot Desktop App, which includes MakerWare printing software and Thingiverse directly integrated. It's compatible with all models except the Cupcake.
The MakerBot Digital Store is a place where you can purchase original designer-created digital content that you can print on your machine. Items include figurines of trucks and pets.
