Just found this link with lots of info about the finale...

http://tardis.wikia.com/wiki/Series_5_(Doctor_Who)

and

http://doctorwhotv.co.uk/tag/the-pandorica-opens

Not sure how accurate it all is but if it's true then it looks like lots of old enemies appear in the last few episodes.

By the way, There is a lot of info in this link that I haven't seen mentioned on this forum so if you don't like potential spoilers then don't click the link...

even if

Probably not. But even if it is true, it will probably be a quick 1 second flashback.

Though, .

If the crack is across all universes and people and events

This 'crack in time' story seems to be very similar to 'The 3 Doctors' story....

And it would seem that from the spoilers that the similarities don't end there.... O My G'od ...

That article doesn't mention Rose.

Maybe the crack is between 2 universes? I wonder if Doc10b could fall through it back into our reality

True, but that cast list makes interesting reading eh?... I think the Rose thing is bulls**t
