You can get a refund on steam for pre-orders through customer support.  You have to ask specifically and it will take a while, but it can be done.  I got mine.

So why did I get a refund?

From this list, this is what mattered to me

No Turn Based combat
No Fog of War
No more custom mercs with I.M.P
Climbing on buildings only on predefined spots
Explosives only on predefined spots
No more weekly or daily salary for your mercs
No learn-by-doing, training or practicing
Unrealistic portraits (You can only recognize mercs by name)
Simple Interface (Watch the Screenshots)
There is no longer a Map Inventory. (You have to drop/change/repair/share items in the tactical view)
No more usable vehicles like Skyrider or the Icecreamtruck
No bloodcats
No mortars
Only 1 attachment for each weapon.
Les weapons as in the original
No more decomposition and no more ravens

I'd also add "no more ability to aim"  (and by aim I mean spend time perfecting the shot for an increased chance of hit rather than selecting to shoot at head vs torso)
Only one difficultly level
