OGL - It is way, way too early in the process for that to be considered or talked about.
DDI - I would be very, very surprised to see any sort of mention of what the electronic tools will consist of more than 3 or 4 months before the release.
In both cases, it's not too soon for a statement of
intent.
If they're going to have an open license (especially if it's not an existing license), then there's a very slow process involving legal. If they're going to have some sort of electronic tools, those tools will take a long time to develop. In both cases, they're long processes - they should be getting started.
That being said, I also think that it is a complete no-brainer for WotC to have some sort of electronic tools presence for Next. DDI was, last I looked, bringing in a couple of million dollars a year for WotC (around 50k subscribers at about $10 a month) in a predictable fashion is not something that any company the size of WotC will scoff at.
Latest estimate I saw was just over 70k, giving $8.4Mish per year. Which, for a company the size of
Hasbro may well not worth bothering with.
It's also important to note the costs associated with DDI. Developing the existing tools was expensive. Maintaining the servers, developing material for the magazines, and applying the errata are all expensive.
There's absolutely no guarantee that DDI has been a profitable venture, taken over the whole of the 4e edition cycle. That being the case, Hasbro may well be hesitant about investing another tens of millions in developing
another new set of tools for 5e.
I for one would be completely surprised if they even considered an OGL model again.
Actually, so would I. But if that's the case, I would like to know.
(Although, that said, I would be very surprised if it wasn't possible to develop support materials for 5e using the OGL,
even if 5e was never formally opened - exactly as has been done for 4e. If they're smart, WotC will recognise this, and if they do then they might choose to formally open the game in order to garner the goodwill such a move would generate.)
