Warner Brothers accidently leaked their upcoming 2010 titles. A good chunk of the titles weren’t exactly notable, but there were two worth mentioning.
The first worth mentioning is F.E.A.R. 3 and if you are not familiar with the series its like a horror first person shooter complete with a creepy little ghost girl. Scribblenauts 2 was also listed but had a interesting tidbit along with just the listing. The list says the title is being developed for Wii, DS and PC.
We don’t know if 5th cell is working on Scribbulenauts 2 as of right now though. Last I’ve heard is that they were moving onto developing games for consoles, specifically a XBLA if I recall correctly.
