I know the OP wanted to discuss what WotC would do, but imagine how the third-party community would look if 4E had never materialized.
Paizo would quite likely still be wowing us with monthly issues of Dragon and Dungeon, and there'd be no talk of Pathfinder (probably). Necromancer Games would have put out a few more huge, high-quality products, likely boxed sets. Guys like Aeryn Rudel, Craig Cochrane, and Roger Carbol, who (semi-)regularly put out spectacular 3.5 material, would still be doing so.
The third-party field for 3.5 would be much richer than it is now were there no 4E.
