A travel question for our German members

Crystal ball time! Here in the UK, today in our national news it has been reported that Angela Merkel has failed in her attempts to reimpose a national lockdown due to opposition from the government.
Will she try again? And if so, when? Is it likely that a national lockdown might be reimposed over Chrismas and New Year? I ask because I have a BA flight to Munich, Dec 31st.
