I read the Hololens 2 has a better pixel density of 47 pixels/degree of visual field. Not sure if I recall if the units I stated are completely correct, but I have no idea if that's enough to render good font quality at all levels of presentation.

Looks like it's probably similar to using a 27" monitor on your desk, depending on the resolution/size of the display

47 pixels per degree (PPD) would certainly be good enough to emulate a desktop monitor. In reality, 35 PPD is sufficient, albeit only capable of emulating low end monitors. 62 PPD is roughly the limit of human eye resolution for a general static image.

I would be surprized if this Hololens is up to 47PPD, but to my pleasant surprise MS did make a big leap (no pun intended) in optics his go-round. So, I suppose it's possible. In my opinion, they are definitely (finally) on the right track in terms of pursuing a virtual retinal display (I.e. laser projection on the retina).

I thought the pixel density is the same as Hololens 1, but the display is bigger.
