It's becoming quite clear it is unlikely to push the One to a huge sales spike or curve, as some were predicting. I doubt it will even outsell the PS4 in the US and UK, the two regions it will sell the most, for March. Here's why I think that.
Let's look at the US, first. If we go to the Gamestop site's Bestsellers List, the Infamous Bundle is #1 out of all products on the site. #2 is also a PS4 bundle. Titanfall rounds out the Top 5 (edit: it now sits at #7.) The Titanfall Bundle isn't even in the Top 10, sitting currently at #12 (edit: it now sits at #4.) On Amazon's Bestellers for March, the PS4 has shot up to #1, while only being available for a few days. Titanfall rounds out the Top 5 (edit: it now sits at #3), again, while the Titanfall Bundle is even lower than Gamestop, at #14 (edit: now sits at #12.) Now, some may say, "But the bundle was available in February, too." That's true, BUT it only hit #71 on February's Bestseller List. And if you look at Bestsellers for 2014, the situation looks worse, as the Titanfall Bundle has not even broken the Top 100 (edit: it now sits at #79.)
Now, let's look at the UK. I'm only going by Amazon for the UK, but if we look at the March Bestsellers List, we can see that Titanfall is doing great at #1, but the bundle is only #34 (edit: it now sits at #32.) The bundle didn't even break the Top 100 on the February Bestseller List. And just like the US (edit: it is now #79 on the US site), the Titanfall Bundle has not broke the Top 100 on the Bestsellers for 2014 List.
So, in conclusion, I think Titanfall is going to have good sales, but in terms of pushing Xbox One HW, I think it's not going to do too much. Maybe push the One back to January sales, or slightly above, but definitely not taking on the PS4 in any meaningful terms. What are your thoughts?
And on a quick note, I will update the positions on Monday (again), so we have final numbers just before release.
