A bit of quick analysis/speculation based off these aerials:
I think it's fairly safe to say, assuming these are indeed coaster footers, that this won't be an inverted coaster. Traditional sit downs have supports directly underneath the track, as seen here, as opposed to inverts having offset supports compared to the ride path and alternating between left/right side of the track.
Second, I don't think much can be said about having square versus circles or any other shape footers, as most companies have utilized more than one shape. But, I found the seeming "random" alignment of the squares compared to the ride path to be interesting and I did a bit of looking through rcdb images to see if there were any trends in companies doing this. I couldn't find any examples of Intamin coasters with this arrangement. Their square footers seem to almost always be parallel to the ride path. Mack and Zierer seem to use these styles much more often.
In fact, this shares a remarkable similarity to Verbolten's opening slow section, which also features footers positioned in seemingly "random" ways.
Of coarse this is all speculation based off concrete
