You've got questions - we've got answers!
Well, they have responses. But while every answer is a response, not every response is an answer. Going in, any of us could have said that the answer to the first and third questions would have been that there would be at least a little more support, but probably not too much, and certainly couldn't have put a date on it.
Coming out, the answers we have to the first and third questions is that there will be at least a little more support, probably not too much, and we can't put a date on it.
Well, I for on, would like to see some new books with errata for at least the PHB, and the MM would be great also. Even better would be PHB i, II and II as well as MMI and II
My group seems to be going to continue 4E for the forseeable future.
Given the weight of errata for the 4e Core Rulebooks, and also the reality that they
may switch off DDI support, it would be really good if they would reprint those books, for people who want to continue.
Given the DDI editorial team is "still discussing plans for 2013" I wonder if the next announcement involves the cancellation of Dragon and Dungeon.
Honestly, I wouldn't be surprised. A lot depends on just how profitable DDI has been. If it had been the runaway success WotC wanted, then there would be no 5e at this point (at least, not one as fundamentally different as this one), because doing so would risk the subscriber base, which would be an intolerable risk.
Assuming DDI has been a moderate success, but given the costs associated with developing yet another new version of the tools, I would be inclined to expect a much-reduced 5e DDI - ongoing e-magazines (maybe), plus a new 5e Compendium and (hopefully) a Character Builder. I'm reasonably confident that that's where the money lies -
players will sign up for an easy way to manage their characters and to access the latest crunch/errata. But the DM tools will be nearly non-existent, as they cost just as much (or more) to develop, but they attract a fraction of the subscribers.
If DDI has been only a marginal success, then I would expect to see DDI almost completely mothballed. The "magazines" will be cancelled, and replaced with a handful of free columns (probably at, or below late-3e rates of release, if we're not already below those). The tools will be left active, but without ongoing maintenance, further errata, or any new tools being developed. Eventually, as subscriber numbers dwindle to the point where it's no longer turning any profit, they'll pull the plug.
And, of course, if DDI has actually been a failure, they'll just switch it off entirely. But I
don't believe that that's the case - if it had been, I would have expected it to take D&D as a whole with it; surely they wouldn't now be spending the money to develop a new edition?
