Bethesda trademarked the name Starfield several years ago, which was the genesis of all the speculation. They've also said TES6 is a very long way away, too, and I seriously doubt they are doing Fallout 5 on the heels of 4. So they must have a different IP in the works.
I think there is something to the rumor that Starfield was going to be unveiled at last year's Berheda show at E3, too. If you watch that it's obvious they had a star/sci do vuve in all the backgrounds and such on display. Yet nothing they demoed was like that. Their show was widely panned as being very anemic too... like it was missing something big enough to justify all the hype.
Eh, make what you will of all that. Ita dun to speculate.
