Holy Crap
Well that's kind of exciting. It's fun being a fanboy sometimes.
So, I'm wondering what the 4th dimension would be. Assuming one dimension is word, and the second dimension is art (or 2D like paper), and the third dimension is minis/battlemaps and such (as in 3D representation), what could the fourth dimension represent for D&D that's not paper and mini?
My guess is that they have developed a way to take your GAME into an "online" world. You can play it by word, by sight, by mini, or by online gaming environment.
