Ya Airbus is in trouble..... they only got 1000+ orders to ship out right now for the 320 family

Airbus has proven they are in control of that sized market, and guess what there are a bunch of US fleet renewals comming up for that size range!
American: 327 MD80s,
United: 94 737-300/500's....... UA will almost surely renew with 320's
NWA: 115 DC9's.... could be 115 A318 to complement their existing 320 fleet
US air: 96 737-300/400.... US air seems to also be favoring airbus

Delta and continental will definetly not go with airbuses, they stick to boeing.

That is a possible another 630 A320 family orders in the next few years!!!!!!
It would be more if the said airlines replace their 757's with A321's... tho i dont see this happening, the 757's are amazing planes still.
