50k here or there is less than a statistical fluctuation in Early Access / DOS:EE sales, the 'real milestones' are spaced 500k apart. If they seriously have their sights set on DM mode, they'll just do it even if 50k short.

The REAL question is if they actually need another ~500k to really make this work in a non-hackneyed way. And they probably do, but that's what enhanced editions are for, haha.
