New Departure Time please help?

Hi all,
I logged in to my booking on virgin Atlantic today to find out that our flight time has changed from Man to Las Vegas. We Fly out on the 28th of April in Premium Economy and although the seat map has not changed, the aircraft type is no longer showing as a Boeing 747-400. Can anyone advise if it will still be a Boeing 747-400 of if it will be different? Also could someone check the load for me please?
Flight number is VS085 on the outward leg.
Kind Regards,
David
