I have the game for a while now for the PS3 and got stuck again in Chapter 7.
The whole gameplay and the story itself are absolutely outrageous and make lot of fun, just this one bug can spoil the whole genuine.
But there is a little bit complicated workaround that have discovered by now I on the Internet with which you do not get stuck in Chapter 7!

Greetings soldier!
This is a rare problem in the PlayStation 3 version of Wolfenstein: The New Order can occur. To circumvent the problem, the following steps are necessary:
1. Download the last checkpoint.
2. Move back and slip it on to Anya.
3. Press the Action button (square) on Anya while you slip.
After the end of the video sequence, the game should be continued normally.

It worked for me :)
