Pretty much as expected, they didn't name it Colbert. And, also as expected, they gave a consolation prize.
Unexpectedly - they didn't name it the second place vote winner - Serenity (which also had geek cred to it).
They went for Tranquility. The... eighth place winner.
The consolation prize was naming a new treadmill going up the station (and being placed in Node 3, perhaps?) the Combined Operational Load Bearing External Resistance Treadmill (COLBERT). With a cute little mission patch to with it.
The pre-announcement (where Colbert was still feigning expectation that they'd name it after him) joke was the best bit. Paraphrased...
"And one day soon a child shall point up to the heavens and say: 'What's that, mommy?' and she shall respond, 'Why that's the Stephen Colbert space node!' and he shall say, 'The same Stephen Colbert who saved the Earth by fighting off the zombie mutant horde and undead dragons?' and she shall nod and say, 'Yes son, and also the most tender lover I've ever known.'
