Title says it all, really. Asus Europe has confirmed at a press event that Jelly Bean will be released for the Prime, the TF300, and the TF700T, but TF101 and Slider users will be left out in the cold.
"Sam from Tablets Magazine was present at the press conference, and ASUS confirmed that not all of its tablets can expect an update to the newest version of Android. The Eee Pad Transformer Prime TF201, the Transformer Pad TF300 and the Transformer Pad Infinity TF700 are certain to receive Android 4.1 Jellybean.
The previously launched models, the Eee Pad Transformer TF101 and the Eee Pad Slider, are not expected to be updated, and will remain on Android 4.0 Ice Cream Sandwich."
