The game wasn't released yet. That actually makes it more important to show the 'official' way to play, especially on a podcast that people will be listening to in order to find out how the game plays.
Why are you afraid to respond to my posts?Or, are you afraid that the majority will disagree with you?
Belt: Usable by anyone, once per dayComparative material:
Belt of Fiends, L15 magic item
Power (Daily): Immediate Interrupt. You can use this
power when you are hit by an attack. Gain a +3
power bonus to defense against that attack; you can
decide to use the power after the DM tells you the
attack die total.
(From "Rose Keep," _Dragon_ 366, p. 43)
Draw your own conclusions.
It seems that in order to remotely justify Shield at level 2 vs Belt at Level 15, you'd have to read Shield without adding "you can decide to use the power after knowing what the attack value is."
