They got it wrong, each of Sony Computer Entertainment divisions operate completely separate. SCEA has no control over SCEE and voice versa.
This is what I hear is going to happen in NA.
-Sony can buy 80GB HDD cheaper in bulk, due to them being more widely used.
-Sony also plans to use the cheaper blu-ray disc diodes in the 80GB model (which costs much less to manufacturer).
-The 80GB PS3 may lack the EE (like the Korean model) chip, and go to software.
-The circuit board of the 80GB also reduces components (like the Euro PS3).
-The console may be packed with the rumble SIXAXIS.
Basically, the new 80GB model will be Sony's more costs effective PS3 in the future, which will probably be sold worldwide as their main SKU (If you see the price on it in South Korea, you can tell its more manufactured at a lower cost). Right now, SCEA wants to get rid of all the 60GB models they have (which contain a regular SIXAXIS). They'll sell the 80GB alongside the 60GB PS3 for now. Once the 60GB PS3 is completely cleared, they'll remove MotorStorm from the bundle, and sell an 80GB PS3, with no EE, at $499.99. Sony will have a cheaper PS3 on the market (so they can concentrate on cutting its costs more), and all the new PS3 consoles could be packed with a SIXAXIS rumble controller (well, after they un-bundle MotorStorm). Sony has done similar in the past, trying to get rid of older units, and that's what it appears they're doing.
SCEE is doing something completely different. They are bundling the current PS3 with two games and a extra controller. Reason they aren't price dropping yet in Europe is because the console just came out in March. However, around the Holiday season or maybe as early as October, they will drop the price of PS3 there and un-bundle it.
Let me repeat this. The 80GB PS3 with MotorStorm is Limited Edition currently, just like the PSP having the Entertainment pack last Holiday season, the PSP slim bundles, etc. The 60GB SKU is still their main SKU for now. It will be a lot longer than people think for Sony to clear the 60GB. They still have plenty of 60GB HDD which they need to use up, before completely going 80GB. SCEA (Jack Tretton) stated over and over again that its limited edition. That idiot Reese (most Sony fans hate him) has no say over SCEA and barely knows what they are doing.
