im not disputing the ps4 is outselling the xone however the fact that its available in 50+ more countries is obv helping sony win this gen so far. and if microsoft couldnt make up a 2m sales deficit in over 50 countries then i guess they really would be selling. however i dont think it really matters much to the consumer only ones affected are the big 2 as majority of games will be released on both consoles anyway
This pretty much assumes that Sony can make significantly more consoles than they've sold.
Being available everywhere doesn't mean they are selling every console they could be. If Sony and MS can produce 7million consoles between launch and now, and Sony sells them all and MS can't, that is really the key situation.
There is talk of MS talking up numbers sold to retailers because there are loads on shelves, talk about production plants being scaled down, etc. Sony could maybe only have made 7.5mil consoles to date and would have sold 7.5mil if they were available only in Japan, US, Uk or if they are available worldwide but still the same 7.5million.
This is the issue, production generally ramps up. Nintendo were making massively more Wii's in say the 3rd year than the 1st year, same for 360/ps3, and it will be the same for PS4 and would have been for XO, if it was selling better.
The reality is we don't know precisely how many consoles Sony have made/can make by now. That they are talking up sold to customer numbers and retailers aren't dropping prices massively, not offering great bundles all the time, haven't dropped the cost effectively £130 since launch(taken as a launch price Xbox + titanfall would be £480, but sold for £350).
The general situation around the world appears to be Sony selling everything they can make, thus their sales are limited by production, not demand, and number of countries it's sold in becomes irrelevant. The converse is true for MS, talking up sold to retailer numbers, consoles in stock everywhere in large numbers, retailers tanking prices to get units sold. In this situation MS launching properly in more countries makes perfect sense, they would bump sales almost certainly... however it might not be significant and might look bad(if they lose in another 30+ markets).
