I got the Otterbox Defender for the protection and cut the screen out of it with a VERY sharp cutter blade. Only slight cleanup by trimming where I cut the screen out. The combination works great. Never had a glass screen before but that is all I will use future phones.
Unless they come with an integrated plastic film (like the Otterbox defender and you can always cut it like johnling said), pretty much any case will fit with a tempered glass protector!
