I didn't say it was incompatible, I said you wouldn't know if it had any quirks. If it's 100% compatible in every way that's great, I just hate spending hours trying to make something work the way I expect it to only to find out its a compatibility issue.
As you've now ordered it doesn't really matter and I hope they do exactly what you expect. If they don't in any way you can report back and answer the point.
Maybe I'm just in a grouchy mood over this sort of stuff as I spent hours last night trying to get a pocket wizard to fire a remote camera which in turn will fire a remote flash. All the proper gear and I'm still scratching my head, but at least I known I'm starting from a known baseline.
