I have not seen any reliable and specific information about the plans of Bitcoin Gold developers.
Well, that would probably be because I they dont have any (or at least as far as I am aware of). Its really just an altcoin with some tiny tweak (imagine trying to release that as a new coin, it would be nearly worthless).

when did bitcoin split before to now split "again"?!!
That would be because
different developers wanted a Billion+ market cap the easy way.
