I think she's implying something here. I mean we must look at it this way... *puts on my for-occasional-and-only-special-events-use thinking cap*
Okay so here it goes. The word divides into two parts, Potter and more... okay so I know the Potter part, but what more? It is read as more Potter if you reverse it. More Potter books? Perhaps about the next Potter generation? Or maybe I'm just thinking too much into this. It may not be any of my assumptions all together. *Takes off the thinking cap* *Puts it back on* Great! Now I can't even go to sleep with all this anticipation and ideas dancing in my mind!
