Autocad 2011 vs Autocad lt 2011...fresh off Japanese site.

I could have popped this online as a pdf, but I turned it into a jpg instead. Nothing earth-shattering in the list, but word appears, that it'll be coming out March 15th or so, or about a full month behind the Japanese release. Why is that???
Oh, and I couldn't understand one romanji word, so I left it as it was translated literally with "(?)" next to it.
