I'm not convinced things will continue to get worse in terms of booking non-Home resorts.
SSR has been fully built-out for nearly 2 years now (June or July '07) and I really haven't seen any evidence that owners there were pulled strongly to their Home resort in the early years of ownership. Many people seemed ready and willing to book elsewhere with their very first reservation. (We actually couldn't get SSR for our first stay and had to do BWV Preferred instead.

)
Throughout much of 2007 and 2008
DVC was marketing Developer's Points (and double Developer's Points) which could be used at
any resort. That was making the 7 month competition even worse for a good 12-18 month period.
The waitlist changes may also help. With DVC eliminating the ability for folks to get on the waitlist for a dozen different resort/room class combinations, it should increase the overall odds of success.
And then there's the reallocation which can only help bookings. If we agree that the reallocation was at least partially motivated by too many people using points for weekday stays, come 2010 some people will find their points don't go as far as they used to and/or overall patterns will immediately begin to change (shifting more members to the currently under-utilized weekends, which opens up more weekdays.)
If we want to label SSR and OKW as the least-desired DVCs, as of 2007 those two represented about 65% of all DVC rooms at Walt Disney World. By the end of this year when AKV and BLT are open, SSR and OKW will be down to 45% of all rooms at WDW.
We Internet folk have already been privy to all of the booking tricks and secrets for years. Not much room for our patterns to change.
Other members would have to make independent changes to their booking habits--in great numbers--in order for all of us to begin to feel the impact. This is hardly scientific but whenever I speak to other members during our stays, they rarely voice any booking frustration which suggests they are inclined to alter past practices. They aren't racing to the phone at 9am exactly 11 months out or "walking" reservations or booking their Home at 11 and switching at 7 mos. They simply call when plans are finalized and the most appealing option available. Go figure!
