Nobody seemed to mention that the new PHB will be out months before the new MM and how that affects the changeover one has at their table. I plan on picking up the new PHB and looking at it and might have players wanting to try out some things, which is cool and overall the path I would think I want. The problem is that the new DMG and new MM may affect how things play with the new classes in the way of magic items and monster power. If I start new PCs using the old rest of everything- is this going to screw up things later when I get the other books and now find problems with play.
I would think that maybe things would be better if I just waited to the 51st anniversary and got all the new books at once. I do not really see this happening though.
