Kojima’s latest project canned?

Has Kojima’s latest project ended up in the gutter before it was even announced?

A tweet from the mind behind the Metal Gear Sold series hints at a possible cancellation of something which the mastermind has spent a year planning. The tweet was made on his Japanese Twitter and is roughly translated as:

“I cannot bear, and cannot be positive. What I prepared minutely spending a year became meaningless.”

We don’t have the slightest clue as to what the title in question is. Could he be referring to his new NGP project, the much demanded Zone of the Enders 3 or his new “taboo” project he had earlier tweeted about?

“The next project will challenge a certain type of taboo. If I screw up, it might force me to leave the industry.”

Guess we need to patiently wait for E3 or TGS to get our answers. What are your thoughts on the matter?
