That character select screen was quite polished. Why would you think it was something that they just threw together for the demo? Seriously. They are very far along in development. They have to make a final character select screen, and they've probably already basically finished that. I'd be certain that they just altered the final version to show fewer characters, possibly tweaked the shapes of the boxes. Why would they do any more work than that?
But obviously it can change.
But this is the Brawl demo character select screen:
This is the full character select screen:
They are very, very similar. There are definitely no major design changes.
The boxes are slightly altered in proportions from the demo to the final, full version, and accordingly the pictures are slightly adjusted in relation to the box. The demo has 6 columns and 3 rows, while the final version has 8 columns and 3 rows for starters, and 9x4 for the full roster. They do slightly change the shapes of the boxes from the starters to the full roster, adding an extra column in the same space.
So I think it's reasonable to think they might end with a full roster of 4 x 13. That's easily done without making major changes to that character select screen. At 14 or more columns, it will start getting too cramped for the names of characters with longer names... but maybe they could do like they did with Donkey Kong and Captain Falcon...
Maybe they'll go to 5 rows, but then the boxes will start to get quite small.
I still say that 51 or 52 characters is basically the upper limit.
