I think the formate is fine they just need to not interupt an interview. While they are on the floor it would be weird to split the interview and say "we'll be right back after a word from our spnsors" but here is a suggestion.
Do the interviews like you have been doing. Then when you are finished with the interview record a 10 second teaser of the product/interview. It would be backwards of the way it is viewed but you really don't know what should be in the teaser until the end of the interview. This would allow you to play the teaser, then the sponsor add, then the interview and it would look very smooth and should be simple to edit.
Anyway I like the video coverage on the floor and Linus's off the cuff presentation of all the new items,
BTW Linus (if you read this) be careful chewing ICE you can cause micro fracture in your teeth ;)
