The drawing of what's called the SGH-i617—the model number for the BlackJack is SGH-i607—as you can see, doesn't reveal much; neither does the documentation in the filing, for that matter. The image does have a BlackJack-like outline, however.

What we do learn is that more substantive is that the SGH-i617 supports AT&T-friendly 3G (HSDPA) on the 850MHz and 1900MHz bands, as well as Bluetooth.

Samsung's SGH-i607, the BlackJack, first made its appearance on the FCC site about one year ago; whereupon AT&T, then Cingular, rolled out the BlackJack a month later, in November.

Maybe the same will happen with the SGH-i617 under the name BlackJack II.

Update: It has been confirmed that, yes indeed, the SGH-i617 is the BlackJack 2.

All that's known so far is that the new BlackJack will run on Windows Mobile 6 and offer a 2 megapixel camera rather than the 1.3 megapixel shooter of the original.
