Biometrics, help!!!!

We were just asked to take Biometrics yesterday.
It is different in our FP, we took pic and signture this time.

Anybody knows if this is just routine for I-485 application now(take this for all application to replace the old FP?)?
Or it means that the approval is coming soon?
I checked the 485 status, it is still pending.
anybody knows?
Anybody submit 485 and was asked to take it?

thank you very very much.
