There's been a long back-and-forth from Sony Ericsson and the dev community as to whether or not the Xperia X10 was at all capable of multi-touch -- the company stance has been that the hardware just can't do it, but still whispers to the contrary have lingered. Consider those murmurs validated: Sony Ericsson Product Blog has announced that the X10 will, in fact, get multi-touch in the first quarter of next year -- with some caveats. The large asterisk that's destined to clarify the minutiae will tell you that pinch-to-zoom will be enabled for browser and maps, but as the blog post put it, "situations like when the movement of the two fingers cross each other on the X- or Y-axis that could cause strange behavior." Third-party apps should be able to join some functionality, too, with the similar limitations (including when buttons must be pressed simultaneously -- that won't work). In the video demonstration after the break, take note how Angry Birds doesn't quite pinch and zoom smoothly. So yeah, it's not all sunshine, but at least there's something to look forward to.
