I think it's absolutely safe to say that it's doing fine in general but the disparity between the PS4 sold to consumers and XBO sold in to retail has got to be concerning, especially given the amount likely spent on the push accompanying the launch of Titanfall (ad spend, bundling, locking up exclusivity, etc.) and whatever dispensation they gave to retailers for the huge amount of bundles out there last month (because I doubt that retailers just ate all that cost).
Plus, another concern for them has to be the network effects that a widening gap would create. Given that both cost for multiplayer and given that increased online buying is likely to encourage the use of one ecosystem over another, the wider the gap, the harder it may be to get buy in from people who have friends with the competing platform.
And though I know the Tier 2 countries may be insignificant in the larger scheme of things, giving Sony a huge head start in countries that are already favorable to them in the first place just makes things worse.
