I just hope they make the Back to Karkand map pack very inexpensive so most players end up getting it; $5 or less. I guess there needs to be something of value as a pre-order bonus.
Now that we know the details of the Physical Warfare pack it seems completely inconsequential. I doubt I'll even unlock all of the weapons and gadgets within 2 months, so those 3 in the pack won't be missed in that time.
Also, good to see absolutely none of it appears to be Origin exclusive so far.
