Nah, just new graphics for old content.
I'm particularly confused by the announcement on the front page saying "Next week the wait will be over!". I wasn't aware we were waiting for anything?
I'm most confused by the duck in the forum version of the image, but not the front page version?
It's possibly general upgrades, unannounced (recently) and untested. But untested isn't really a problem since no feedback from the test phase is never seriously taken into account anyway...
