Two recent observations: that lead me into thinking Embarcadero is changing the Delphi and RAD Studio version suffix to Seattle.
Thanks to Achim Kalwa for getting that to my attention in Looks like Delphi XE9 will have support for Windows 10 RT: …
It led me to my observation that until now, sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches always had the real product name as banch name.
Today, Horacio Filho who observed the Seattle part in the new documentation URL http://docwiki.embarcadero.com/Libraries/Seattle/en/Main_page which currently is only accessible only for the groups writer, l10n, RADBeta, ConnectBeta, Employee.
The docwiki URLs historically also use the real product names in the URL.
In fact there is a little trick: removing the product name portion of a docwiki URL usually brings you to the most recent documentation (which might be more up to date and provide more information even for older products). So removing the XE7/ part of http://docwiki.embarcadero.com/Libraries/XE7/en/Main_Page will usually bring you to the most recent documentation http://docwiki.embarcadero.com/Libraries/en/Main_Page.
If they both Seattle URLs still use product names, then the new Delphi version is called Seattle is added.
