While the online version will definitely be Flash, but I wonder if the offline version will be different. It will probably be a SWF converted to EXE/APP, and it will not be Squeak, but I wonder what it will be in.
Note: The reason I posted this topic is that while I was going through the unread posts, and something about porting Scratch to C++, and it said that the offline version had not been started.

Like you've said, it could be a SWF, or EXE/APP file. My guess is that there will be an exe installation files for windows users, and app files for Mac users, and a swf file for linux users.

An Air application then. Probably an swf for Linux users though.
