According to this Kotaku story, EA's stopped work on C&C-based FPS Tiberium because, essentially, it wasn't up to scratch.
"EA has suspended work on Tiberium effective immediately," said Mariam Sughayer, EA spokesperson. "The game was not on track to meet the high quality standards set by the team and by the EA Games Label. A lower quality game is not in the best interest of the consumers and would not succeed in this market.
"This decision will result in some individuals being released. However, EA will make every effort to place talented people on other projects. Eligible employees will receive severance and outplacement support."
