So in the next few weeks we have two major games coming out for both PS3 and 360 and both are getting special edition HW bundles, Tales of Xillia and Gears of War 3. Now with Xillia and its bundle only seeing a release in Japan and Gears seeing a worldwide release you might think that this won't even be close. Think again. Historically Japan has gobbled up limited edition consoles and the week-on-week boost that they give, at least percentage-wise, is usually significantly more than the boost you'll see from special edition consoles in other regions. Here's some examples of boosts from special edition bundles or consoles in Japan, and not just limited to PS3.

FF7 Advent Children BR bundle (PS3): http://www.vgchartz.com/weekly.php?date=39915®=Japan&date=39922 (45k boost)
MGS4 bundle (PS3, Japan only): http://www.vgchartz.com/weekly.php?date=39649®=Japan&date=39614 (67k boost)
White PS3: http://www.vgchartz.com/weekly.php?date=40384®=Japan&date=40391 (23k boost)
Monster Hunter Tri bundle (Wii): http://www.vgchartz.com/weekly.php?date=40020®=Japan&date=40027 (71k boost)
Tales of Vesperia bundle (360): http://www.vgchartz.com/weekly.php?date=39663®=Japan&date=39670 (18k boost)

I notably excluded the FFXIII and GT5 bundles because it's impossible to determine the boost they gave due to their holiday release. Now let's look at the boost that some of 360's SE consoles have given WW.

Halo 3 LE console (game not actually incuded): http://www.vgchartz.com/weekly.php?date=39348®=World&date=39355 (66k boost)
Halo Reach Bundle: http://www.vgchartz.com/weekly.php?date=39355®=World&date=40440 (105k boost)
FFXIII bundle: http://www.vgchartz.com/weekly.php?date=40244®=World&date=40251 (12k boost)

So which limited edition bundle will give the bigger boost? Here's something worth noting, estimates for Xillia's first week are in the same area as MGS4 and MHTri.

Difficult one.

I say Gears, but not by a huge difference.

Gears.

vesperia.

I voted similar boosts cause i cant decide

Is this boost only related to how many people buy the limited edition bundled console?

Xilia. ,most who wants gears has a 360. The boost will be very small.

xillia ,because japan loves there special bundle systems, specially on ps3.
gears of war 3 system will do good numbers though, i think it might be close since this most likely is the last gears of war game for the 360 and the next game be on there next system.

People said the same thing about Halo: Reach and look the huge boost it gave. 

Gears...by a country mile
