The publishing of Gurps 4E books is supposedly back on schedule now. That means 1 new book every other month. Considering SJG track record of constantly not being able to meet their publishing dates I wouldn't hold my breath waiting for GT: Interstellar Wars to show up in January.
Also, while they have already stated that they are working on High-Tech (TL4-7) they still refuse to even comment on whether or not they are even working on Ultra-Tech. I personally prefer 4E to 3E, but it's going to be a few years even if SJG sticks to their schedule before you should expect all of the G4E books you need for Traveller to be available.
