Looks like there's a leak confirming the official MSRPs of the GTX-1050Ti and regular 1050: http://www.kitguru.net/components/graphic-cards/matthew-wilson/gtx-1050ti-specs-and-pricing-confirmed-in-presentation-leak/
So the GTX-1050Ti is coming in at $139 and given its performance level that's a pretty good price considering there are "premium" Rx-460 parts going for almost that much. Apparently the GTX-1050Ti's launch price is $20 less than what Nvidia charged for the GTX 950 when it was new.
The regular GTX-1050, which is probably a more 1-1 competitor to the GTX 460 is coming in at $109, which should put it in close price parity to all but the most basic of the Rx 460 parts.
