Not sure, but I thought they were going to extend the walkway outwards and make it much wider.
Also I beleive one of the makeover plans for Metrotown station involves building a concourse level under the current station so the ticket level would be alot larger then the current one and include some retail.
The coffee shops at stations make sense even if you can't take the drinks onto transit, you can now have the coffee shop as the meeting place when your friend whose's always late doesn't show up on time and you end up walking around the station for 10-15 minutes looking like a tourist who doesn't know what train to get on.
