I suspect that Pelosi may try to appease some in her party by allowing hearings on possible impeachment charges, but unless things look a lot worse for Trump than they do now I doubt there will be an actual impeachment vote in the House. Besides, hearings, especially ones focused on the emoluments clause and to what extent the Trump Organization has enriched itself thanks to its boss being President, will accomplish all that might be desired politically while denying Trump the "victory" of not being convicted in the Senate.
I agree that the above is the most likely option.
