Believe the previous poster was asking questions; not presuming information in reaching a conclusion. However, as assumption can also mean arrogance, some apparently have this well in hand even as seasoned vets....

Indeed, and "seasoned vets" are the most susceptible to such presumption... 
That said, I do believe that everything known to date about the Keep can be summarized as follows:
1. It'll be an on-line ("cloud-based") repository.
2. It'll be platform-agnostic, allowing free transfer of world-state settings between all.
3. It'll allow the player to specify ALL the choices (that have any forward impact) from previous games, whether or not a) the player actually played those games; and b ) if so, whether or not those choices were, in fact, the ones the player made! 
4. It'll allow multiple world-states to be maintained "on-file" (for all the "What if..." fans out there!)
5. It'll prevent incompatible world-states from occuring, (e.g. Alistair and Anora were married at the end of DAO, but Alistair is ruling solo in DA2.)
6. It will NOT be a stand-alone or in-game application (sorry, players without an internet connection, however many or few of you there are.)
7. Most controversially, it will NOT allow direct import of previous saves. Besides the technical difficulties of implementing such a thing across platforms, the incompatibilities introduced with the flawed save/import mechanisms in the previous games, (see #4) make this impossible.
Anyone know anything else?
