I'm not familiar with those plans but I can tell you there are currently no covered walkways to or from aircraft except the last 15ft in front of Intl Arrivals and the plans for this round of development shows no external covered walkways.
As you say I suspect the economic climate, loss of WW and other such factors may have put a halt to those plans.
