Engadget found some posted and then removed data from ASUS that clearly seems to outline their pending lineup of tablet devices to be unveiled at CES.  

CES 2011: ASUS will have tablets, lots of tablets at CES - Mobile  3

You can see from this screen grab that there are two designs that will use a stylus for input (or at least an option for input), one that looks like a large phone (EP71) and other maybe a 7-10-in form factor (EP121).  The EP102 is a slider tablet indicating a hidden physical keyboard that is revealed at a slight angle while the EP101 is listed as a “transformer”.  My personal request is that it is Ironside.  

Engadget has another screenshot and a link to the video (though it might be gone by the time you see this) so be sure to stop by and see what there is to be had.  This is likely the very beginning of a TON of tablet details that we are going to barraged with at CES next week.  Stay tuned!
