I'm also curious about this. Does this mean the free beta versions will stop working or I'll start getting a prompt to "upgrade" to the paid one? I've been using the free beta version for the past year or two.
3. Will the latest version of Swype Beta (v1.4.9) expire?
Yes. As with each previous release within the Swype Beta program, the latest version of Swype Beta (v1.4.9) will expire. The expiration date for Swype Beta v1.4.9 is September 14, 2013.
