How many Chinooks to Afstan soon?

The MND:

...
MacKay told Reuters on the sidelines of a security conference that six to 10 [emphasis added] medium-heavy lift helicopters, such as Chinooks, and some unmanned aircraft would be delivered to Afghanistan by February 2009.

"Hopefully we are going to have some of that equipment arrive late summer, early fall and our intention is to have all that equipment in place by February 2009."..

Yet the US Foreign Military Sale notice speaks only of six aircraft (see Update at preceding link). Hmm.
