Tim Cook's (non)response (via TechCrunch's live blog)...

Will not comment on the roadmap." No promise of a new CDMA iPhone in summer. Tim Cook: We chose CDMA because the LTE chipsets forced some design concepts that we would not make.

When will be able to see an LTE-enabled iPhone? A. We're not commenting on unannounced product.

My guess would be batter life. The first generation of LTE chips probably suck that thing dry in a couple hours.

My guess is Tim Cook didn't want to talk about iPhone 5 features that Mr. Jobs may reveal this summer.
