Would be my guess as well, though I'm unsure about the CDU/CSU getting more good stuff done than other less shitty parties. The last administration did pretty well mostly thanks to the Greens even though the media kept bashing it to no end, and I do not want to imagine a world with a CxU/SPD coalition during the chaos after the full-scale invasion of Ukraine.

Also I think The Left is far less likely to get a significant share of votes than the Greens.
