It's definitely looking closer now but people have to remember not to view the daily updates in the same way as the monthly updates. The daily updates give us an idea of how the monthly update will look. Ignoring the Destiny bundle for now, we've had nearly 14 days of 2 PS4 bundles (that affect this month) above the Halo bundle and it looks like we may soon be seeing the halo bundle above the 2 PS4 bundles. Depending on their positions, I'd say it's still an advantage for the PS4 in terms of deciding the final monthly update. Throw in the Destiny bundle which made it 3/1 at some points and I'm still inclined to think the PS4 wins. It's all going to come down to pre-orders. To sum up:
2/1 (3/1 occasionally with Destiny) to 1/2 (+preorders) = Likely PS4 win. But also bare in mind that it's still 1/1 in favour of the PS4.
I will say though that I'm almost certain the PS4 won't lose ground this Christmas like they did last Christmas but will in fact gain ground.
Monthly so far:
#21 PS4 Destiny Bundle
#27 PS4 TLOUR Bundle
#28 PS4 Star Wars Bundle
#40 XB1 Halo Bundle
#57 PS4 Nathan Drake Bundle
#65 PS4 Black Ops Bundle
The PS5 Exists.
