Are the series connected?

Phantasy Star Online and Universe have a lot of small connections to the classic series - techniques, reused names, the cake shop, and so on. Do you believe there are any larger connections, or story tie-ins, with the original games? Or, do you think each of these three series are completely separate with no real connection other than easter eggs for classic fans?

I go with the final option. Separate, with easter eggs.

I have to agree, from what I've seen so far. They may try to tie all these games together one day, but I don't see how they will manage to work it all out.
