I have a Nokia Lumia 630 running Lumia Cyan on Cricket Wireless and can you give me a guess on when I should receive the update. Thank You for your feedback.

No clue.

First, we'd have the see the rollout begin, meaning the 630 probably won't be too far behind. My best guess is 8.1 Update 1 + Denim going out later this year, albeit starting.
Second, given the track record of US carriers in rolling out updates, you're probably looking at a few extra weeks or months.
