After ASUS's Singapore Facebook stated an Android 4.0 OTA would be hitting the OG Transformer as late as March, it now seems that ASUS UK's Facebook page is indicating that said update will be landing in the next week:

A quick refresher on the TF101 ICS Update that you are all so patiently waiting for. Our engineers are working hard on getting this ready for you as soon as possible and are still aiming for a February release. As always as soon as we hear any further news or a definitive date we will let you know.

While different regions do have differing release time frames for various reasons (eg, language support), you'd think ASUS would go about announcing this sort of information in a way that might be slightly, uh, organized. Still, good news for Transformer owners holding out for some Android 4.0 action, given that they've been waiting since CES.

We'll see if ASUS makes good on this promise in the coming week.
