For the year 2014, the PS4 will in all likelihood maintain over 50% marketshare with 60% as of current, but I don't see it hitting 50% LTD.
I'm not going to bother doing the math, but it would have to sell something closer to 70% over 2014 to negate the extra one year of sales posted by the Wii U, which is a bit unrealistic.
As much as the PS4 continues to surprise, sales wise, it doesn't seem likely.
I'd look at the production/shipping projections through 2014 first, which probably aren't available. I don't see the PS4 failing to hit a near 100% sell through on production for 2014, so it will depend upon production numbers for the Wii U and XBO, assuming they hit a near 100% sell through as well.
