While Google may have given the Motorola Xoom the first nectar-filled glaze from its recently released Android 3.1 Honeycomb, almost everyone knew, by intuition, that the other smartphones and tablets will eventually have their taste of Honeycomb updates soon. Google did announce at its I/O 2011 developers’ conference last week that the updates will trickle down to the other phones and tablets but never gave a definite date.

It turns out that the wait won’t have to be long for ASUS and Acer. Both companies have reportedly conveyed their intentions to freshen up their respective tablets–the Iconia Tab A500 from Acer and the Eee Pad Transformer from ASUS–starting early June.

PCWorld reports that Acer has confirmed the June updates, while ASUS announced the upcoming update via its Facebook page. Neither company declared any exact date for the release. Acer did not specify whether the update release will be simultaneous worldwide. Both ASUS and Acer will provide over-the-air (OTA) updates.

Both Iconia Tab A500 and Eee Pad Transformer are strong Xoom contenders. All three tablets run on dual-core Tegra 2 processors and carry a large display width of 10.1 inches.

With the Android 3.1 Honeycomb updates coming in early June, both Iconia Tab A500 and Eee Pad Transformer will start enjoying the new and sweeter perks that Xoom is now enjoying: better performance, more apps displayed in the task switcher (as opposed to Android 3.0′s restriction to show just 5), vertically and horizontally flexible widgets, USB peripherals support, support for Adobe Flash 10.3, and more.

Meanwhile, another contender in the tablet race, the T-Mobile G-Slate / LG Optimus Pad, has not whispered anything down the grapevine as far as the Android 3.1 Honeycomb update is concerned. To date, both LG and T-Mobile continue to assure the public that the G-Slate’s Honeycomb update will be “coming soon.”

With Honeycomb updates starting to trickle to the other tablets, what sweet predictions can you make for the 10.1-inch tablets competition?
