I have now voted that it will get stuck because I do not believe it will escape north yet.
I forecast it will travel west (anti-clockwise) round the coast towards the Weddell Sea over a number of years, getting frozen in during the winters.
For comparison, B15AA has spent 20 years getting from the Ross Sea to the South Atlantic, where it will soon melt away. (I did find B15AA on (Ant)arctic.io on 2016-08-13, @ long. 37.11554, lat. -68.27076, which is closer to the Weddell Sea than D28. On the image for 2019-01-19 it appears at long.-40.16057, lat.-64.97348 approx., having traveled west over the north of the Weddell gyre!) It has taken yet another year to sail free northwards.
I wait to be proved wrong!
