Hey! I had my I-751 yesterday and asked before as well. End result, they let me do the N-400 and same-day oath, I am now a US Citizen!
And believe it or not, I am 99,9% sure we had the same Immigration Officer conducting our interviews, haha! I-751 got approved on the spot, and after I had to wait a little, I got called in for my N-400 interview.
Thanks for your help @Lazybones18!
