The Lion King is out the week before but OUATIH is skewing for a different demographic so it could be fine.
After all, The Hateful Eight came out a week after The Force Awakens and that managed to do okay. This will do even better since it has more star power in Leo, Brad and Margot.
Hateful Eight probably suffered a little being released so close to Star Wars. it didn't made near as much as Django Unchained, for example. And Tarantino himself wasn't too happy about the situation:
