In all honesty, I can't say I'm especially disappointed.
According to an interesting Superannuation Tweet , it seems developer Slant Six was working on a Medal of Honor installment for the PlayStation Vita.
The source cites a Slant Six developer who included concept art for the unannounced MoH handheld title in his online portfolio. His LinkedIn profile says he worked at the Vancouver studio between 2006 and 2009. Slant Six is well known for their solid SOCOM games but they also produced the stinker that was Resident Evil: Operation Raccoon City . Besides, after the disappointing Medal of Honor: Warfighter , maybe EA was right in putting the franchise on temporary hiatus.
And really, I'm not sure this is the kind of game the Vita needs right now. We've got Killzone: Mercenary coming, after all. How's about a few big RPGs…? The PSP had lots of great ones.
