I'm guessing the texts are still placeholders
Could be. Still, the evidence seems point to the contrary. Some effort was put into that design because it's also used in the menu screen. So why go for a certain style if it's all going to be scrapped? Also, seems like one of the easier changes and it's been the footage for awhile now.
On the other hand, the neon could have been put it cause it's easier to test...or...they haven't settled on a style or gotten a graphic designer yet and it is indeed a quick placeholder.
Eh, just have to wait and see.
EDIT: I just checked out the GDC videos and the menu screens have a new style. Looks much better. Now if that simplistic font style will transfer over to the ingame overlay....awww yeah.
