But also, you know, shooting. Saying that the TES games are FPS hybrids is like saying cars are bicycle hybrids because cars borrowed the idea of wheels and locomotion.
But back in the speculation thread, I didn't realize that Bethesda still had until the end of July before they have to reapply for the tm. I was thinking it was June, for some reason.
"Shooter", only because no one prior to Bethesda had thought about doing a fantasy-themed FPS/RPG, hence why the TES games are so unique. With the large increase in melee-heavy FPS games, it is not unreasonable to expect that the term may take on a new meaning of "First Person Shooter/Slasher".
A car is not a bicycle hybrid. Making that comparison is absurd due to the large number of differences between the structure, use, and specific purpose of cars and bicycles as well as the fact that neither "car" or "bicycle" can be argued as being allegorical to "genre".
TES is a hybrid between RPG and FPS because it draws heavily from both to arrive at an exceptional idea. Additionally, unless you have never used magic, bows, or thrown weapons, I expect you to know that you do plenty of "shooting" in TES games.
However, back to my main point, "Fantasy" is a thematic style and "RPG" is a genre. Everyone who has been proposing possible titles that match the GI tweet has been (subconsciously?) limiting their ideas to Fantasy RPGs when the quote does nothing to suggest what the genre will be.
