I believe that Musk has made it abundantly clear that the BFR is their goal: https://en.wikipedia.org/wiki/BFR_(rocket)

I read that Musk wanted to scrap the Heavy development to free resources to focus on BFR, but there was sufficient immediate customer demand to justify continuing.

Most of us are quite glad that he did.

In the post Falcon Heavy press conference, he specifically mentioned scaling up to a Super Heavy with two additional side boosters, four in all. Sounded like they had designed for that, from the way he just threw it out there.

Seems odd to me, since FH is an interim vehicle until BFR comes on line in 5-10 years.

It's important not to get too intoxicated with your own success. If BFR is as successful as their Falcon series, it'll be ready in 5-10 years. If there are unanticipated challenges with BFR (after all, this is literally rocket science), having a lower-risk approach mitigates that risk.

I thought they were targeting launches much sooner than 5-10 years out for the BFR?

They are, that doesn't mean you should expect them to hit that target.

Musk doesn't seem to set timelines with the expectation that they will be attained. They are always best case, but development never is.

yep, they still need to make money.

Imagine seeing 6 boosters land simultaneously. Just nuts.

7 including the central one.
