Indeed. It could also be the first route that explores a "Premium" pricing but with the pre order discount bringing it down to the standard price...if you pre order.
DTG haven't changed their DLC price in forever so I presume they will stick with the usual £25 even though there's a lot of work having gone into the route and assets.
We might be lucky with the following pricing Pre-order £22 and some shrapnel Normal price £24.99 Week after release £8 or close to (here's looking at the full price I paid for Sherman)
And who might that " anyone " be? Until DTG sticks the price in the window, no-one on the forum can know. Just assume it will be the normal price until you know different.
