How will Extra Time affect FW:5?

I know I have a VERY long wait to see Series 5 on DVD, but I was wondering how what happened on FW:Extra Time will affect the new series...

Will Bruno and Lucy be suddenly gone - even though last we saw on FW, Lucy was about to be murdered by gasoline fumes? And does Bruno get away with murder/manslaughter of Conrad?

Will Harley and Shannon also be gone since he apparently took off with Katie in ET?

What about the Jackie/Seb scandal - Seb's dad wasn't anywhere to be seen on the playing field during practice - does that mean he no longer works for Earls Park?

It seemed odd that Tanya's sister has apparently been living there all along - will she be featured in the new series?
