Honestly, I don't care about the next game. Before you pick up the torches and pitch-forks, let's think about this for a second.
1) All Bethesda games have released as bug fiestas, but they get patched and made into good games a couple of months after launch.
2) Bethesda wasn't responsible for the abortion known as ESO. That turd may have been set in the same universe, but bore no marks from Bethesda.
3) The current engine used for Skyrim/Fallout 3/anything else is finally beyond its lifespan. HD graphics are taxing it too much, and they're already performing huge amounts of work just to get it running. This means they can't cobble together spaghetti code to make it keep going. A new engine means a new opportunity to finally fix some of those underlying bugs that plagued the game. With all the cash Skyrim brought to the table, an investment for another decade long engine isn't an unreasonable investment.
4) Bethesda isn't flooding the market with this property. They aren't releasing these games yearly, and their DLC matters. They do a good job keeping people psyched for the future.
5) Fallout 4 will bouy people until the release of the next game. Like it or not, Bethesda is likely to use the same engine on both games. Considering that just the possibility of Fallout 4 being announced drove people mad, it will create a huge enough space upon its release that the Elder Scrolls will be temporarily forgotten. While not easy to say, we are idiots. Dangle a shiny new game in front of us, and 90% will stop demanding whatever it was we were focused on before.
All of this adds to a simple conclusion; these games will come when they come. Bethesda has a track record of good games, and that should be trusted. If they demonstrate otherwise, we can act accordingly. Starting threads like these won't change anything (or we'd have Halflife 3, right?), and they only serve to raise expectations that may never be realized. I'll wait patiently until Bethesda releases something.
