Mega Man Zero/ZX Legacy Collection is out later this month for multiple platforms. Ahead of its release date, here are the details on its day one update.

With the recent release of the Mega Man Battle Network Legacy Collection, the next collection of games starring Capcom's Blue Bomber seems obvious.

With the release of Mega Man Battle Network Legacy Collection this week, it joins an already-impressive catalogue of Mega Man re-releases from the past several years.
If you combine the titles from Mega Man Legacy Collection 1 & 2, Mega Man X Legacy Collection 1 & 2, and Mega Man Zero/ZX Legacy Collection, you've got a total of 24 classic games available to fans and newcomers. With the addition of the 10 Battle Network titles found in the latest release, this brings the running total up to a staggering 34 games. That's a heck of a lot of Mega Man!
It really feels like Capcom is looking to release as much of the Mega Man back catalogue as possible on modern consoles, possibly to preserve the series going forwards — at least in digital formats. There are still quite a few games from the series that remain untouched, however.
The Legends and Power Battles games should make the jump. Those were fun games. I remember playing the Power Battle games at a local mall before it randomly was removed. It had a bunch of Capcom games on it.

With little signs of a new Mega Man game coming, the various legacy collections keep the blue bomber relevant until a new game is announced.
The file size of the game is confirmed to be 3.1 GB on the Nintendo eShop and 2.8 GB on the Microsoft Store.
The day one update for the game will patch it to version 1.01 and include the following changes. It is just a little over 100 MB.
Added online functionality to new Z Chaser mode
Unlocked online leaderboards
Unlocked World Record Chaser mode
Various bug fixes
