I think it has every chance of surprising people, initial reviews seem favourable. It clearly has several features that depart from both original P210 and Legend designs, however judged on its own merit it may be superb. Though the locking system is different it is in no way inferior from an engineering standpoint, just look at the X5/X6 line. The purists will be butt hurt and cry, they always do, but had SIG not used the 210 moniker I bet everyone would be singing praises.
People also easily forget the wage and social benefit discrepancies between Western European labour and North American labour, which accounts for a great deal of the cost disparity. Additionally, when the Legend was being imported the Euro was relatively strong compared to the USD. With modern CNC machining and a reduced cost labour force I think it is very possible we will see something that is able to rival it's predecessors at an aggressive price point. If not, use the $1000 you saved for a trip to Gray Guns?
