There is a good post on this topic here.
I agree that the likely future for W-space is some classic consolidation. If you are a solo or solo+alt corp trying to maintain a presence in W-space, the time may quickly come for you to join forces and pay homage to a "parent corp", otherwise you will likely face challenges defending your territory.
The most likely arena for this will likely be in Class 3 or higher w-space systems, where the w-space systems can generate an ISK yield to support larger corps.
It has grown crowded out here in w-space! Favorite analogy, posted by Xonus:
"...In this game, we have a limited number of systems and spaces for people. I wouldn't mind if someone set up a cabin in the forest somewhere and occasionally hunted. But, if everyone set up a cabin in the forest somewhere, it would cease to be a forest."
