Not mine, but those of Topeka Citizen-Journal local sports reporter David Streeter:

ArenaBowl XXII (7/28/2008): Chicago Rush over Dallas Desperados
Two of the best teams in Arena Football will face each other in the ArenaBowl. The Chicago Rush, who made plenty of key offseason moves, capture their second ArenaBowl.

I haven't yet settled on who I expect to see in the Arena Bowl. Chicago is an easy pick with the off-season signings, but the league is stronger than ever this year, so anything could happen before this year's AFL championship.
