1) Only if you've edited the wiki. If you've never edited, it will show the "no info" state (second screenshot in the post above)

2) The new avatar size is 150 x 150px. If your avatar was larger than that, it will be sized down. If it was smaller, it will remain smaller, and will not be stretched (you may want to upload a new one, though).  The avatar upload tool will also be improved with this change, and will auto-crop instead of stretching non-square images.

3) I'm not sure what the customization situation will be like, but we'll see soon enough! (There's definitely some room for being creative with it)

4) Since this is Wikia-wide content, no. However, we're looking into ways to add optional wiki-specific question areas on the lower part of profiles in a future release.

5) Birthday is month and day only.
