Well regardless of when it was written, the "sub-$2m" figure is still contingent on him having an expectation that the Kickstarter campaign would only return $2m.
Like, hypothetically, if Yu Suzuki were a lunatic and "expected" that the Kickstarter would raise $50 million, then his statements would still be true even if Sony were putting in $40m.
That's obviously not the case, but if his expectations for the Kickstarter were to raise $5m, then the amount of outside funding is "sub-$5m", not strictly "sub-$2m".
Basically, I believe that his statements in the interview are true, and it's very possible that the outside funding comes to less than $2 million, but it would also be very unusual for him to "expect" to come away from the campaign with "only" the $2m minimum funding, and so his statements in that article could reasonably mean that his outside funding is anywhere from $1-2m (or less, but that would be unusual) up to $5-6m (or more, but that would also be unusual).
