Yesterday, Motorola revealed its plans for a number of current devices, including the Motorola DROID and CLIQ.
The Motorola DROID will receive a second maintenance update sometime in the near future. Flash 10.1 is also headed to the DROID. Later, an Android 2.1 upgrade will be made available as well.
The Motorola CLIQ will also receive an upgrade to Android 2.1. Hopefully the DEXT will receive a similar upgrade.
Lastly, the Motorola BACKFLIP, just announced yesterday, will also get an Android 2.1 upgrade later. For now, it will ship with Android 1.5.
Specific timelines were not provided by Motorola for these upgrades.
