New users are also being put in III.16, so the champion from there will probably be human.
Assuming that, then there will be 4 auto promotion spots and 13 bot promotion spots (for the bot champions of III.3 - III.15) into div 2. I'm not 100% sure in these edge cases of very high bot populations, but my expectation would be that bot cleanup would go through as many human managers who were in III during the season as possible, and then would start "re-promoting" teams that relegated from II if necessary. Please don't treat this as official confirmation though, I'm speculating, and I'm not really sure how it would handle choosing between teams that "would have relegated" out of III if you had a lower league vs teams that did relegate out of II when choosing order for the bot cleanup.
That said, as long as you win your conference's regular season, you'll definitely promote regardless of the playoff result, unless there is a huge wave of new SVK users between now and the end of the season such that it fills up d.III
