From their website:
We want share with you guys the results of a few months of hard work.
Here is the schedule and a list of topics for the next year’s worth of Over The Wire (OTW). Most of the content for each edition is already complete. We do reserve the right shuffle the schedule around in order to add some cool surprises and extra details in each issue though
Both AE-WWII and AE: Bounty will be supported in future OTW releases each month. There are still some surprises in the list of topics because we don’t want to give everything away just yet. Not on the OTW release list, but still in the plans for 2010, are the revised competitive campaign guide and a summary of errata and FAQs.
Check out their posting for full details.
