The 5th release of D&D is due for release in "Summer 2014", which means sometime soon. As far as I'm aware, it does not have a definite name yet: it might be D&D 5th Edition, or retain its name of D&D Next.
Currently we have the dnd-next tag, which has the synonyms dnd-next-playtest and dnd-5e. It would be very messy if questions about the playtest & the release get mixed up in one tag. So, let's not leave that too late - it would be inconvenient if we had a flood of 5e questions on the first release days before anyone remembers to change over the tags.
Could we action this suggestion and rename the dnd-next tag to dnd-next-playtest, and decouple it from its synonyms, leaving dnd-next and dnd-5e ready to use (and create anew) when the game's released?
