I dunno. FF7 aint gonna hurt TLoU2 sales tbqh.
I also think they will want Tlou2 further away from PS5 since PS5 will inevitably allow for a spike in tlou2 sales.
Though May/ June wouldn't surprise me either.
I just don't expect them to launch those games that close together, but stranger releases have happened. Also, I think a June release would be fine (the original released 5 months prior to the launch of the PS4 and the system went on to become the fastest selling home console to release at the time).
