Since he's not going to continue being the "Colbert" from the Colbert Report, I have my doubts. On the other hand, there's no doubt that his "real" personality is likeable and enticing.

If you haven't seen the Oprah interview, it's worth watching in its entirety .. https://www.google.com/search?q=oprah+colbert+interview

Colbert and Fallon also have a good repertoire and I'm interested to see if that continues while sharing the same time slot. If they can continue their comedic rivalry and him pull off not being "Colbert", I'm all in. :-)
