Hate to disappoint you guys but I really dont see anything being announced at MWC.
MWC is a more GSM sponsored event, while there are possibilities of Wimax programs, the main focus is GSM products.

If Sprint were to announce their 4G phone, I think it would be at CTIA Wireless. I just went to the website and saw that both CEOs of Sprint & Clear will be making Keynote Sessions on March 24th.

However HTC will be having a press conference tomorrow at MWC, so its quite possible they may reveal something about Supersonic. It'd be great if they did.
