This past thursday Capcom released a changelog of what they're calling the juicy changes made to the original game.
So here it is:
-Various attacks and skills for all weapons have been rebalanced for all weapons.
-Made the Ur-Dragon corpse's collision boundary smaller so players can now pick up drop items more easily.
-Undead enemies will now come out of the ground with higher defense stats (super armor mode). -When Saurians die after being knocked down, they will now use a special death animation for when they are on the ground.
-Goblin Shamans will appear in the Witchwood.
-Eliminators will appear on the Tainted Mountain.
-Pyre Saurians will appear on the Tainted Mountain.
-Golden Knights and Silver Knights will appear in the Everfall (before the destruction of Gran Soren).
-Gorecyclopes (condemned type) will appear in the Shadow Fort.
-Living Armor will appear in the Catacombs.
-Wyverns (strong type) will appear at Bluemoon Tower.
-Wyrms (strong type) will appear at the Watergod's Altar.
-Drakes (strong type) will appear in the Everfall after the destruction of Gran Soren.
-Adjusted how often pawns will talk by spacing out less important lines; in effect, making them seem to talk less.
-Adjusted and balanced the equipment and skills of all of the high-level pawns that are available to a player when they're playing offline.
-Adjusted how much it costs to hire a pawn that is higher-leveled than yourself down to a more realistic scale.
-Added a Monthly ranking to the pawn's Top Ranked section.
-You will not gain Affinity with Assalam simply by talking to him anymore.
-Adjusted how much Ferrystones cost and how much they sell for. (Purchase price: 20000 >5000 | Sell price: 3500>1250)
-Adjusted how much Premium Rings and Premium Earrings cost. (Purchase price: 1,500,000>150,000 Rift Crystals | Purchase price 3,000,000>300,000 Rift Crystals)
-Tweaked stat increases for weapon upgrades (increases weaker upgrades, decreases ones that were too strong). Tweaks affect 68 different weapons.
-Dramatically increased base stats for 12 weapons obtainable by defeating the Dragon.
-Improved base stats for 10 Magick Bows
-A Portcrystal that allows players to return to Cassardis has been added just outside Cassardis's gate
-A character/warp point that allows players to travel between Bitterblack Isle and Cassardis has been added to Cassardis's pier.
-Added a removable Portcrystal to the following areas: The Gran Soren Everfall (before a certain plot point. . . .), The Shadow Fort, The Witchwood, Hillfigure Knoll.
Having not played the original I can't speak to most of those changes, but less chatty pawns is probably a good thing judging from the demos and all the videos I've seen. Also, holy shit them some serious price cuts.
