I personally don't see much need for this. Rumor and speculation are just that, and won't amount to anything more until Square says otherwise. Square will release new info when they please, making any speculation moot. Furthermore, production seems far enough ahead that it is unlikely Square "snoopers" will see good ideas in discussion threads and implement them. But I guess you never know.

Some people may enjoy running in circles with unconfirmed rumor and so forth, but it seems like a waste of time to me when it would be easier to wait patiently for more info which will be forthcoming. That's my two cents and I don't doubt some people strongly oppose my viewpoint.
