The term “flesh” has replaced “sinful/human nature” in quite a bit a places.  Good/bad???  I think that it certainly will make the literalist happier.  Search for “flesh” and narrow it down to Pauline Epistles. The TNIV is no longer available since the NIV 2011 replaces both NIV and TNIV.  However if you would like an on-line version it is still accessible at Biblica.com

There is also a video introduction by Douglas Moo and some translator notes as well

Another interesting change is to Hebrews chapter 2:6b from the TNIV.  The TNIV caused a quite the stir when it released this one:

…”What are mere mortals that you are mindful of them,
human beings that you care for them?

where as the NIV 2011 reads:

…“What is mankind that you are mindful of them,
a son of man that you care for him?

Feel free to post more interesting findings in the comments, or reactions to the NIV 2011 as well.
