What is the current logo requirement for selling an app made with A8 Commercial.. I cant seem to find any mention of it...

Do we need to display a logo, and if so, where do we get it?

I think you have a startup window always displayed if made with commercial. with pro you can hide it and imo no logo needed.

I think JCL said in an older thread that the gs3d logo must be visible for non-pro version, the rest doesn't. Here is the default startup logo (low reso though) http://media.moddb.com/images/engines/1/1/256/Logo.png . Here is another one on this forum (also low reso) http://www.conitec.net/images/a8icon.png . I also saw another animated/video one from an user on this forum which looked alot better than these.

You can use my improved version
