I personally don't know where that third fact came from, but it sounded like pure speculation, so I removed it from the article. Anyway, Akihiko created both the NerveGear and SAO, so there's nothing that prevents him from working on both at the same time. Especially since making a floating castle was his actual goal and to achieve it, he needed a game and for the game, he needed a console to run it, so the development of the NerveGear and SAO should be tied together.
