Thief 4 - Worrying @ Kotaku

Kotaku writes a piece titled Worrying About Thief 4, discussing the apparent loss of several highly placed developers and suggesting Square Enix has been sitting on a concept video for a number of months:

After two-plus years of work on the project, Thief 4 audio director and composer Paul Weir left the Eidos Montreal in March. The month prior, lead level designer Adam Alim went to WB Games Montreal. He apparently is not the only lead level designer to hop off the team — Pierre-Olivier Clement, the previous lead level designer, apparently moved to another project at Eidos Montreal last year. Among other departures: two senior concept artists exited Eidos to a freelance career after nearly two and three years, respectively; a senior technical level designer left last month; a senior animator went back to Ubisoft last September; and a senior level designer moved to something else at Eidos in August.
