I had the chance to talk to a Huawei rep. His unofficial response was along the lines that it something that still remains on their radar. All the carriers which Huawei has distributed products to in the US (which are on 2.3) are asking about ICS updates.

I think there is still a possibility of ICS for the Mercury. This supports what Cricket Wireless' social media team states. It is quite dependent on the manufacturer to produce the update.

I don't think much came out of the Froyo update for the Ascend (MetroPCS) which has already achieved end of life status. There might have been some headaches for users and the carrier. Hopefully the lessons learned here will help with a successful deployment of ICS if it came to the Mercury.
