Is this a good time to buy?

I've been wanting to get a micro 4/3 for years now and I'm finally ready to buy. Is now a good time to buy the OM-1 Mark II, or is this something they'll be updating anytime soon? It looks like they have a pretty good deal on the body with the 12-40mm lens right now. I'm also looking at the new 100-400mm lens that's coming out this month to go with it.
