Absolutely, shocking devastating news. As somebody else said it's all the more shocking that it could have happened to any one of us here (albeit this was a freak accident).Shocking news. Rip.
Hopefully a tribute to him will be a revolution in helmet technology.
Thing is, if he'd been wearing the new helmet launched by his helmet manufacturer it might have hit the grill. I think the ICC, ECB, Cricket Australia and every other body need to decided what the safest helmet spec is and have a blanket rule saying that's the type of helmet you have to wear. If the spec is that the grill has to be a certain size and/or cover a certain area it would still allow different manufacturers to make them so you wouldn't get the price shooting through the roof if they said "x company's helmet is the one to use".
