The verb look has been used to talk about the future for a long time. Perhaps the most common use is in the expression look forward to (something). This use may be based on the metaphor that time is a landscape we move through. As such, our future should be visible to us. This is probably the same metaphor that underlies the use of go for the future in expressions like we're going to get to that in a moment.
Despite its venerable history, futurate look began a significant upsurge in about 1980, particularly, in the looking + to infinitive construction.
I noticed that this seems to be particularly common with are.
Especially, you are.
And even more specifically if you are.
By this time we are looking at a small minority of the cases. But I wondered if it might tell us something about the meaning of the looking futurate as opposed to the going futurate. When I started looking at various corpus genres, though things got a little to complex. Maybe you have some thought to add.
