This is correct. One guy I listen to a pod for said the episodes keep getting better and he's seen all 3.
Yeah, I'm guessing with every episode that passes and with every layer of the onion that gets pealed off, the series will look less and less what it is now and more MCU typical. Here is an article which describes this:
WandaVision Ending Is A Full MCU Action Movie
WandaVision will evolve from sitcom to action movie.

In an interview on Jimmy Kimmel Live!, Paul Bettany explained how the show will evolve from the sitcom-style to a full-on MCU action movie. The Vision actor confirmed Kimmel's theory that the sitcom-world of the show will not make up the whole storyline. "That’s 100 percent correct," said Bettany. The actor went on to say, "We hurtle through the decades, and we hit different genres of sitcoms and then Vision begins to think that this is getting a little weird, you know. And in the end, you end up in full, MCU action movie."
Teyonah Parris, who plays the grown-up Monica Rambeau, called the show "a full-on action movie, mixed with sitcoms."
