A handful of Blizzard's developers wants to communicate with the map-making community and answer questions regarding the editor and the arcades to help the community.

Quote from Blizzard Entertainment

With the launch of the Arcade in 1.5.0, a few of the nearest and dearest from the StarCraft II development team will be joining us on the forums and focusing on answering questions about custom map development. If you have any technical questions about the editor or the publishing process, these folks should be able to provide you with some help and guidance.

Are you guys going to be passing out information about upcoming features or replying to questions that are essentially feature requests -- or are you going to reply only to questions about how the editor works?

All of the above. I'll primarily be focusing on answering technical questions about the editor since that's where I'm most qualified. If you have feature requests, fun ideas for the editor, arcade suggestions, or anything else, we definitely want to hear it. When we have something exciting to share about the editor, we'll also post it here on the forums.

The main goal is to allow all of you to have direct communication with those of us who work on the editor and arcade.

You can find their thread here.

Blizzard stated that banks can now save up to 1mb per player.
Before, banks couldn't hold more than approx 8.5kb per player in multiplayer games which might have been caused by a bug.

We might see more arcade maps which store a tons of data in future.

Quote from Blizzard Entertainment

The issue was brought up and in-fact the limit has been raised. You should have access to 1MB per bank (per player) with a maximum of 36 banks total. This is then shared by all players and distributed as you see fit to do so.

Teamliquid's Administrator R1CH created a convenient tool to change the gateway and assets used in the game. By changing the assets language, the sound's localization will be changed.

Sadly it doesn't work with the editor at the moment. But you can still change the editor's gateway via registry addition/changes until the editor's can change the gateway by itself.
