How likely is it that a prepaid ZenFone 2E would receive a future 5.1 update?

I'm really considering just going ahead and uninstalling the bloatware on my ZenFone 2E (ATT PrePaid). It's currently on 5.0.1, but I was wondering if you all know from experience if a prepaid device is even likely to receive an OTA update? If not, then I'll go ahead and uninstall the bloatware. I haven't yet due to the hoping of a future update and didn't want to cause a brick in an update process.
