Regarding Nano-ITX... its a good news bad news thing.
Yes it was officially launched at CeBIT, Yes they are now in production. Yes the specs should be up... and that's the good news.
The bad news is that there is significant demand from VIA's existing customers and some very key strategic potential customers. So... the first few batches will be going to those people and it will probably be a few more months (sorry) before they start to find their way into channels for the individual consumer.
