I would imagine that boomsound will return since htc would be crazy to get rid of that.
Camera wise 21 mp
Not sure about the front camera
why would they be crazy to get rid of boomsound? it's not like they did well with it.
that said, I agree they should keep the front facing speakers, but according to HTC, it's not possible to have boomsound without the black bar. they keep that black bar and it'll be dead on arrival, so either they need to figure it out, and keep the boomsound but remove the bar, or ditch the boomsound.
either way, the black bar has to go.
I think they really just need to keep things simple, kinda like moto. a 5" and 6" version with large batteries is a good start. again, remove the black bar, improve the camera and freshin up the design. not suggesting they get rid of sense, but trim it down instead of adding useless features. include the features/specs people expect in 2016 (I can do without 1440p, at least on the 5" version) and most importantly, don't make a thousand different phones and price it reasonably.
a mid range phone along with these two, and maybe an economy version and that's it. more phones complicates the brand, especially when some are only released in Asia.
