I'm disappointed in Bethesda for doing this, but I have no doubts that the main Fallout and Elder Scrolls games will remain as they have always been. Bethesda have always been very clear that they don't want their main games hindered by alternative titles and spin offs, which is why Obsidian made New Vegas, and the ES MMO is being made by a special set up division just for that game. I hate the free to pay model, and I'm disappointed that Bethesda are jumping on the bandwagon, but I'll still be able to play my favourite Bethesda games the way I always have, so it's not a major issue for me.
