I agree in part to this, my response was based on the OPs stated time frame of 30-90 days, other than the 1520 and the soon to be released (early January ) 929 there are no other WP slated to be released any earlier than May-June 2014 based on the Snapdragon 800, furthermore unlike android, the WP OS is optimized to run smoothly on all WP device regardless of hardware specs, also at present there are very few apps or games that are currently available that can/will take advantage of the new quadcore processors, as such, if the OP were to purchase a current upper end version of a WP now, they would be eligible for a upgrade ( with the new upgrade plans by US carriers ) in 12 months which should give the OP a much broader range of choices of phones as well as allowing the market place to flesh out more apps capable of taking advantage of the new processor, i understand your argument of "end of its lifecycle" unfortunately, in my view, this game of waiting for the next big thing cannot be won, there will always be a bigger faster phone "right around the corner" and unless you have very deep pockets and can afford to purchase a new phone every 6 months you will always be disappointed with your purchase if you engage in this mentality
