Lego Halo Anyone?

Kotaku reader frostcircus sent in an excerpt from what purports to be a marketing survey regarding possible future Halo titles. It's unclear to me whether this is something a marketing company prepared at Microsoft's request, or something they did independently to gather market intelligence, or what.

If the former, it may mean Microsoft is seriously gauging the potential of further expansion of the Halo universe after Halo Wars and Halo Chronicles. If the latter, it may mean nothing.

Can Lego Halo, an April Fool's joke this year from 1Up, be that far removed from at least potential reality?
