Well now Arriva have launched it I suppose I can tell you all a bit more about it 

Frequenta will be our new high frequency brand, to be launched initially in Darlington but will eventually be used at other depots around the North East. Services to be branded in Darlington are 2, 3/3a/3b, 4, 9/10, 13a/13b

You'll have noticed that all of the Solo's have been recently gaining repaints minus the cowhorn - all of these will be used for the new brand, along with the Ecocity gas vehicles have been losing their logos, they will be gaining branding for Frequenta service 2

2843 is the first to gain the brand, shown below (used on services 3/3a/3b today). 
It is generically branded for all routes, though I understand all of the branded buses will have the spider map on the rear, regardless of branded route. Route specific branding will be across the top of windows, using the colours shown on the spider map, though the cowhorn (in the same swoop-style as Sapphire) will remain in sandstone, whereas I think it would be better if it was to be in route colour.
