The model introduced first with 4e (highly expandable rules system, heavy digital support, treating a system like software that can be updated, etc.) will be the model we see going forward. This is how things will be done from now on. There is no going back. Those who do not adopt this model will not be considered forerunners in the RPG pack.
1. Highly expandable rules system that has, upon being expanded in a major way, through PHB 3 and Essentials caused a fracture in their customer base... Meanwhile the rule expansions in the APG and UM books for Pathfinder have caused no such fracturing.
2. Heavy digital support... Well you did say heavy and not good. In all honesty with my HeroLab CB (Which I actually own), CombatManager, the searchable PFSRD and/or PDF's with copy and paste... Not seeing WotC as having such a big lead in this department. I mean when was the last time the
Monster Builder sorry... Adveture Tool
s had any actual new tools added to it? And many of the actual fans of 4e have been overall dissapointed with Dragon and Dungeon under WotC.
3. Treating a system like software that can be updated... Yeah, again this is not universally accepted as a positive by many of the fans of 4e, especially since with it's exception based design there are just too many areas (mostly powers) where changes can be made to be kept up with. At a certain point people want some stability, even if it's not perfect.
You see ideas in and of themselves aren't what leads the way into the future, it's implementation that does... Hey but then again, just like with 3.5, Paizo might step in and actually make the DDI model work, then I agree it probably would be the way of the future.
