Quite bizarre omission that one. Liverpool is getting a store before Newcastle, even though the Trafford Centre isn't that far outside Merseyside whereas Geordies have to go all the way to Sheffield for their nearest.
I guess it's just waiting for the right location to become available as in Glasgow.
I think the factors involved with this is that :-
1. It's going in a £1Billion shopping center that ties in with 2008
2. Merseyside has a dense population of 1.5 Million
3. Lots of creative students, design professionals etc...
4. It's easy for North Wales residents as well
This is all from the Daily Post article ^
Surely Newcastle must be up there next in line for a store
