It announces this issue is now for sale, but I haven't seen it in a store yet. We're just getting the first issue of the year at the end of April, jeez.
But it's a pretty nice preview, touching on many stories I'm looking forward to, especially The Door and Murky World. There are cover images too. I expect to get the cover "A" at the store:

I just hope I come across this new issue soon.
