This is fantastic news, especially as it is situated so close to the London airports.
I know there is a huge debate about which IP's will be used, especially since the WB Potter tour is nearby. But I have absolute faith in Universal and trust whatever they have up their sleeves.
My own thoughts are that they will use Classic IP's such as Jurassic & Jaws and then add some Dreamworks and new IPs to the mix.
A Potter hotel though could be a brilliant compromise.
