Probably not because they have not given you adequate notice.
I think after Nov 29, if the new test is approved, then they will probably advertize it on the USCIS Website, have a notice of the new test with the receipts that USCIS sends, at the fingerprint session etc.
So I would suspect that the only people who need to worry about it are, at the earliest, those who are fingerprinted after the new test is approved. More liekly it will be those whose applications are received after the new test is approved.
