Have we figured out if the impact grenades stack impact or if it's just impact 1 for the entire die pool?

They stack. Whenever a unit fires a weapon, each mini contributes that weapon to the pool. For example, two speeder bikes shooting each contribute Impact 1 (as well as 1 of each die), for a total of 6 dice and Impact 2. So, if a 4 man squad of stormtroopers is throwing Impact grenades, the attack gains Impact 4 (since each mini is contributing that attack)

Yeah they stack. There's an email in the compilation thread. Also a photograph of Alex Davy confirming it with, I think, the guy from BOLS?

Can you link the thread? I've been looking everywhere for that email.

Sure. We've been compiling emails we've received in this thread. I encourage anyone who has an email response to post it there as well.

Not only do they stack but they share the keywords of other weapons in the attack pool. So snowtroopers with a flamer and impact gernades throw out a lot of back dice with x impact and blast. Their move twice and shoot means they have a range 2+ bubble of death. Weiss on the AT-ST can do a 3 weapon attack with impact 4, blast and 3 red, 5 black, 3 white at range 1-2 when fully loaded.
