Technically, he only said that it won't be part of the Metal Gear Solid storyline. He never said that it was not canon nor that it wasn't part of the Metal Gear storyline. Besides, should we list Metal Gear and Metal Gear 2: Solid Snake as non-canon? Those games weren't called Metal Gear Solid, and thus technically weren't part of the Metal Gear Solid series.
