As the patch has been released in the past with and without the data update, I think the chances are the folks at SI towers are trying to iron out as many bugs as possible and make everything work as it was planned to.
There's always more tweaking and fixing that can be done until the data has all been collated, updated and checked.
It's only going to be a couple of weeks now, I'd rather they finished some more ironing of the bugs then released 8.0.2 only for me to start a thread on the bugs forum twenty mins later entitled:
"WHY HASN'T THE PRMOTION/RELEGATION BUG IN IRELAND BEEN FIXED!?"
