There is no publication date as far as I can see, but the Lucretian scholar David Butterfield is "finishing" the new Oxford Classical Latin text of Lucretius. His previous book is a textual history of the poem;
The Early Textual History of Lucretius’ De Rerum Natura (Cambridge: Cambridge University Press, 2013)
The current Oxford Classical Text is the 2nd edition of Cyril Bailey's from 1922. David Butterfield's edition will not be an 'update' or revision of Bailey's text, but rather a complete rework starting from his deep knowledge of the manuscripts...or so I gather.
A recent critical edition was published in Germany in 2019 by the scholar Marcus Deufert; Butterfield's English-language commentary will be welcome and timely.
