At CES they leaked lots of information for it and as far as I can tell, none of it was true e.g. No GPS, no mention of multi-touch mouse, no digital TV support, no built-in wireless broadband, etc.  On top of that, the buzz on the net is that it is limited to 1GB not expandable memory which is just crazy given most users will want to do what ever they can to boost performance.  I hear more version are coming but cannot help but think the phased roll-out is more for marketing reasons than anything else.  

So in my case, I held off purchasing the mini 9 for the mini 10, the mini 10 is not as good as they hinted so I will now not buy either.  Great way to attract customers!!!
