Realistically they will beat April NPD, possibly by a lot.
April NPD was about 115k. If I'm not mistaken that was for 4 weeks. April sales were already depressed due to the pricing screw up where they allowed the price to go from $449 deals back up to $499.
May sales are depressed due to he new SKU announcement.
June NPD will be up as they'll get the new SKU boost, the pre-order sales, as well as it counting 5 weeks instead of 4.
