Well here's something interesting. Shireknight posted up on the Org this morning that CA is running a poll on the .com. The purpose? To determine if people want all those fancy units for NTW that were "retail specific" as a general DLC. Whether the DLC pack they eventually decide on will cost you money isn't addressed, however, this could still be a good thing.
Why a good thing? Because if such an effort proves worthwhile that means CA may adopt a similiar attitude in the future with future games. Could this mean a Total War world free of retail specific DLC? Who knows! But I find it insanely interesting none the less.
Below you'll find Shireknight's original post on the org, as well as a link to the .com poll.
"We are currently running a poll on the official Total War forums to gauge interest in releasing those NTW special units that never made it into a generally released DLC pack. Please check out this link to the poll and vote for the option you prefer.
If you don't vote then you can't blame anyone but yourselves if they don't get released."
