Apart from the fact he's standing right next to the Krogran who drops male Ryder off a ledge. That's pretty shady. Kind of... antagonistic, you might say.
I suspect the dude getting tossed off the cliff isn't broRyder - that one, extremely generic haircut just isn't enough to go on, for me, and the fact that he wasn't part of the three-member squad in the leaked footage makes it still less likely - but I do think the scene's meant to hint at N7 dude having a certain edge. He might not be an outright antagonist, but I doubt he'll be a straight-up ally either.
I like her and why DOES the Tempest have an N7 paint job when Ryder isn't N7? ~makes X-File noise~
To me, the paintjob doesn't really read as 'N7', at least not in the sense that the ship's necessarily associated with the N7 programme. It's the N7 colours, to be sure, but the Normandy (SR-1) had exactly the same paintjob - which is, I suspect, why the Tempest has it; it's a callback* - and it's not like the crew was made up entirely of N7s. I doubt they go around repainting every ship someone with the N7 designation happens to serve on.
In any case, if Ryder's going to be an N7, I suspect it's something we'll earn at some point, rather than something we have at the beginning. It'd just fit the idea of our being 'greener' than Shepard was at the start of the original trilogy a lot better, thematically.

*And a very welcome one, since I've always wished they'd repainted the SR-2 in the original Normandy's colours in Mass Effect 3, instead of blue with a side of Alliance logospam.
