I think the abandonment of Roles and the same Power system for all classes are the biggest differences between Next and 4E. That's why I think the New Coke comparison to 4E is appealing. That doesn't necessarily mean D&D Next is going to be 3E lite. My play test did have that old school AD&D feel to it with a lot of improvisation. That's something that to me 4E lacked.
IME even old school players in 4E just used the powers on their character sheet instead of coming up with new and interesting ideas. These same players were doing that in Next which was fun. I say that as someone who has played and DM'ed 2nd, 3rd, and 4th. I like elements from all and if the Next gets the right mixture of all three then it could be pretty awesome.
Agreed, especially the second paragraph. SO many threads where people argued that under 4e you "could do whatever you liked", yet for all that I encouraged players to do so, they will still just used the power that were on the sheet in front of them. You experience was exactly mine
That said, I do agree with the article. Im not a 4e fanboy, that game just lost me. The analogy that 4e was the "New Coke" of the D&D world was a good one : looked great on paper, but they should have done there research. That said, I do think 4e brought some innovations to the game that were pretty good, and it does seem like when they are "bringing all the old versions together" that 4e is contributing the smallest part of the pie.
