Interesting... the DDI Compendium still says that daze ends a grab, under the "Grab" glossary entry, but it cites only the PHB and PHB3. The more recent "Grabbed" glossary entry agrees with the Rules Compendium that daze doesn't end a grab. Looks like they should clean that up in DDI.Daze does not end grabs - not as of the rules compendium or maybe before that, but the original line that grabs end when you get dazed has been excised.
