Is there a reason it's not roughly a disc if they use the whole wafer ? They could have 50% more surface.
To quote their official response "If the WSE weren't rectangular, the complexity of power delivery, I/O, mechanical integrity and cooling become much more difficult, to the point of impracticality.".
Packaging method can't handle non-square dies?
