They did technically lie because Windows Central asked Microsoft about everything being changed to February instead of February 22 and Microsoft claimed they never said February 22. Jez Corden then showed them their tweet and they said that was a mistake and February 22 was never the date.They said that date wasnt suitable any longer. Phil also said that the feel of the game wasn't perfect so that's what was being worked on. He wants it to feel like Crackdown and so do most Crackdown fans I'd bet.
This is untrue considering Phil Spencer himself said February 22 was the date and they didn't anticipate so many games coming out that day.
