We have a few more interesting details about the Wizarding World of Harry Potter opening details. First, as I posted, there will be a live stream of the events.  This next tidbit comes from Ice Cream Man:

One event that ICM will be apart of is a press conference that will be during the day on Thursday. Rupert, along with Tom Felton and Michael Gambon will be one of the press conferences that we will attend. There will be several others with various stars including Bonnie Wright and Matthew Lewis. For those wondering, there was nothing on Emma Watson being there for these but we’re not sure of the grand opening event.

Also the Today Show will be live on that day interview Rupert and his harry potter co-stars including Daniel Radcliffe and Michael Gambon!

Next we have some news from Mugglenet:

Universal Orlando has announced that composer John Williams – who scored the first three Harry Potter films – will be at the Grand Opening of the Wizarding World of Harry Potter Wednesday night.
