According to this post from GottaBeMobile, they pointed that Asus dropped a hint that there will be new features coming to the new Transformer tablet. And it did. It did not say it was going to be months away. No vague promises like Motorola or Samsung.
Perhaps, Asus taking Android update seriously is why Google appears to be working with them on their Nexus tablet.
Maybe this is what'll be needed to light a fire on the rest of the Android players.
