Should I get the Nokia Lumia 1520?

It's almost a year now that I've been using my Nokia Lumia 920 but I feel like changing to another phone after seeing more Nokia Lumias being introduced into the market. The latest is the Nokia Lumia 1520. In terms of software, whatever is offered is also available for the 920. In terms of hardware, this is a 6 inch phablet with 1080p full HD display. It also packs the ability to add removable SD card for additional storage. Equipped with a 21 megapixel PureView camera, how am I not tempted? If only they can make the phones thinner and lighter, then I'd immediately pick it up.
