unimaginative2 indicated in the Sheppard Subway west thread that Downsview Station was designed to accommodate a future Sheppard line so this seems the most cost effective plan. Besides it seems silly to send York students all the way down to Wilson to turn back. Meanwhile people heading downtown are only marginally going to have to go further west before they head downtown.
Well, connecting those passenger flows could have been one of the goals, but that does not mean the tracks were configured to accomodate the connection to Sheppard line. It looks like the Sheppard tracks will have to continue west of Allen, turn south-west and surface somewhere south of Sheppard, then turn south and continue west of the existing yard, before they can make a connection.
Anyway, the important part is to get the two lines connected. The choice of Downsview or Wilson as a connection point is a technical detail.
