It's up on ESPNU as well. It's smaller than the old BottomLine, but they've increased the overscan protection so in all it's probably a net loss of screen space.
It's SportsNation a new show? I just noticed it on ESPN2.
EDIT: Using my on-screen guide as a rudimentary measuring tool, the ESPNEWS BottomLine is several pixels lower than the ESPNU BottomLine, which is itself at least a pixel or two lower than the ESPN2 and ESPN BottomLines. Which probably explains why I'm getting some bleed through underneath the ESPN and ESPN2 BottomLines.
