The new and quite pricey Garmin Edge 1000 is available for pre-order April 2014.

Image Source: velonewsSlightly larger than the Edge 8xx it boasts new sensors and metrics (eg current gear), remote control, better connectivity to mobile phones and a VIRB camera link. It’s more of a ‘hub’ for all these devices and is moving towards being an ‘all-connected’ bike for example with tight integration to Shimano Di2 and Garmin Vector components.

I think the Garmin 1000 is far better than the 810 but a bit larger. Koo Bikes done a comparison of the 510 and 810 which made me go for the 810 http://blog.koo-bikes.com/first-impressions-garmin-vs-mio-how-do-they-compare/ . I love the idea of being the center of everything on your bike from the virb to your mobile phone.
