Digitimes, Shuttle is about to close shop and is looking for potential buyers. Acer and ECS are mentioned as rumored buyers if this is indeed the case.
It would be a shame to see Shuttle go, as it offers some rather unique products, although the XPC's are generally too expensive for what you get.
ECS already has its own small form factor business unit and has produced a range of SSF barebones in the past with various sucess rate.
Acer could do with the R&D from Shuttle as well as its designers, especially as Acer has been moving heavily into small compact systems, but with quite lacking designs.
