Anyhow, a 4.whateverTF Neo is in a lot better position than PS4 with only 1.8, and with the market advantage it has it will probably be the baseline target. The huge cost of making games for modern consoles coupled with xbone's marketshare disadvantage could mean the extra 2TF for xbone two might not see a whole lot of use.
What market advantage, there are exactly 0 PS4 Neos in the market. Or did you mean the PS4 1.8TF would be baseline target for 1080p?
