Wizard got this sketch. Does it mean an Ultimates 4 or a reappearing of Spider-Woman in USM?

No one knows but with the whole Ultimatum going around don´t be surprised to see Jessica appear in Ultimatum.

Also in Comic-Con it was said that a Post-Ultimatum Ultimates series would come out so does it mean its Últimates 4 or an on-going series?

Questions arrise while marching toward Ultimatum....

Note: I´m no expert on this but isn´t the logo on this Ultimate Spider-Woman the 616 Black Widow logo?

Maybe it´s not Ultimate Jessica Drew behind the costume but Natasha instead since this (images below) was a sketch for Ultimates 3 and other than Mystique we haven´t seen her.... Was this sketch only made for Mystique rather than Natasha?
