Has this Twitter account been teasing Call of Duty: Infinite Warfare since August?

CAUTION: Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2 spoilers from here on.

Activision has started teasing Call of Duty: Infinite Warfare ahead of its expected announcement next week – and may have been doing so since August 2015.

Interestingly, the account follows just 12 other Twitter accounts: Infinity Ward, Activision, Call of Duty, Call of Duty eSports, Sledgehammer Games, Raven Software, High Moon Studios, PlayStation, Beenox, Call of Duty Endow., Beachhead Studios and something called ‘Infinity Initiative’.
