Samsung might grace the Galaxy Tab 2 (10.1) with a quad-core processor before launching it
UPDATE: The US version of the Samsung Galaxy Tab 2 (10.1) will remain dual-core and its shipping date is still May 13, with preorders starting May 4, Samsung clarified for us.
The Samsung Galaxy Tab 2 (7.0) might be giving Amazon's Kindle Fire the creeps with its budget pricing, but its larger brother Galaxy Tab 2 (10.1) will likely see a delay.
It's all for good, mind you - Samsung is rumored to swap the originally planned dual-core processor in it with a quad-core endeavor, so this will inevitably mean some retooling and a bit more testing, hence the launch delay.
Quad-core is good for marketing purposes and as far as production costs go it is not much different than dual-core, especially if Samsung uses its own Exynos processors, but even if it has some Tegras lying around, the difference in assembly price should be insignificant. The 10-incher is codenamed Espresso and apparently scheduled for June launch.
The Samsung Galaxy Note 10.1 is also said to receive a spec bump to the quad-core goodness, so it's anyone's guess if this will delay the tablets' announcement, or Samsung's engineers will manage to fit them on time.
