The info comes from a different player from OP who bought the book. Not having seen the book myself I can't guarantee it, but I see no reason the guy would make it up.
From everything I've read here and elsewhere, the Dreadclaw just isn't the SM drop pod equivalent most of us want it to be. We can only realistically alpha strike one squad, (Chosen seem like a good choice) unless you fork out 30 meltas just so you can have a second alpha striking unit. Don't think I won't buy 3, either . But those points (and dollars) would probably be better spent elsewhere.
However, there is the attack capability. One pod alone isn't going to do much. But drop 3 near some weiner troops and then skim all over them all game long. Or use its ability to drop to strategically set a unit up to jump across the table using skimmer rules and grab an objective. With a unit of CSM it will be ob.sec., and a unit marked with Khorne can pop out and flame/melta/charge/doubletap+overwatch. It will take 2 turns to move and unload, but how many other transports do we have that can jump across the table and not be at risk for crashing and burning?
Is CSM the new flavor and tourney champ? Maybe (probably not), but 7th rules and this IA13 have given us a **** load more options.
