Notice he specifically referenced enterprise, nothing about supporting WM in the consumer space. Seems to me they are now trying to position WM as purely an enterprise OS and are ignoring the (still) millions of non-enterprise owners of WM phones.
Lets not kid ourselves, after WP7 launches you wont see any new consumer WM devices or support, only devices geared for enterprise use like rugged WM devices. Right now they are just marking time, as Windcape said if MS came out and said they are ditching WM in October their sales would plummet even faster than its currently doing.
