Do I need to have a Ubiquity gateway to use this? I will be upgrading everything to Ubiquity in the future, but need a modem now

No, you do not need a Ubiquiti gateway to get started with the UCI. I'm in the same boat - needed a new DOCSIS 3.1 modem, but future-planning a Unifi system. Bought the UCI because it was compatible with Xfinity. You'll play the standard games with Xfinity to set it up (the necessary CMMAC address will be displayed on the LCD). That being said, the UCI will then be operating in an "unmanaged" mode. With a Unifi Cloud Gateway, I believe you'll be able to see more detailed statistics, manage networks, and access settings. I plan on buying a Dream Machine of some sort eventually, for this purpose.

What are the dimensions and weight of the Ubiquiti Cable Internet (UCI)?

The dimensions are 442.4 x 80 x 43.7 mm (17.4 x 3.1 x 1.7 inches) and it weighs 1.5 kg (3.3 lb) without the mounting bracket, and 1.6 kg (3.5 lb) with the mounting bracket.

What is the maximum download and upload speed supported by the Ubiquiti Cable Internet (UCI)?

UCI supports Comcast plans up to 1,200 Mbps download and 200 Mbps upload.
