Best way to check for Falcons in the new 360 is the power supply and lot number on the small white sticker on the outside of the Box. Just by looking if it has an HDMI port might not be good enough.
Though some of Lot #741 say it uses 203w power supply but when you open the box up the power supply reads 174w.
I think at Lot #742+ has 174w power supply printed on the outside, but double check if it doesn't.
As for the Halo Editions, just got a bad feeling about them. $450 for no games and only 20GB, geez what a rip, so who knows if they got Falcons.
Oh and keep your eye out on Dell.ca, they had a special where they threw in Halo 3 and HDMI cable, on top of the Forza 2 and Marvel Alliance Go Pro Bundle

Though it expired (think it was a one weekend thing), Dell could bring it back. Or just print off that page and go to Future Shop or Best Buy. If they refuse to match the offer, just pretend to get angry and make a scene.
