I doubt the price of the Sopra will increase in relation to this. The differential in pricing is currently five thousand greater with a model of similar specification. Additionally, pricing at each individual tier is based on what the market will bear with consideration to all peer competitors. Canton Ref K series is competitive to the Sopra series as do the B&W 800 Series. These factors will play a greater role in pricing then in house competition.
Stereoplay has already produced its first review of the Kanta No.2 with a base set of measurements and ratings. Based on those figures, Focal has certainly achieved its stated goals on bass performance and it has most of the hallmarks of current Focal designs.
The bass falls of -3db at 38hz and -6db at 34hz and should provide a fairly good in room performance. Its pretty even handed and doesn't show the mid bass boost used buy some. On axis, the frequency response is quite flat to 30 degrees to either side. Getting up to 60 degrees off axis does show some of expected response falloff at the lower treble and upper treble. Its expected given the 2.7khz crossover between the mid/tweeter and is a compromises made between driver dynamics and dispersion. It has slightly less emphasis at the upper treble, which is used often to balance in room response. Might be a slightly less airy sound as compared to the Sopra.
Plenty of competition at this price point. B&W 804 D3, Canton Reference 7K or 5K, Revel's upcoming F228Be, PSB Imagine T3, and the Dynaudio Contour 30 are all within the target area. Focal is adding a some additional style to their product as a differentiation.
