I know my heart says the plot for next year's animated Transformers movie is going to be a mix of Aligned and IDW's origins for Megatron and Optimus, but it's not going to stop me from consuming every ounce of Pre-War content I can get my grubby little hands on and make a bingo card for it. (The Free Space will be "[Sniffles] You Two Are So Divorced" btw. Don't lie to yourself and say they aren't)
