AT&T follows Verizon Wireless: offers $99 unlimited calling plan

Just a quick note as a follow up to news this morning: Verizon introduced a $99.99 unlimited voice plan as well as what I think is an overpriced $39.99 plan for 50 MB of data, and now I see that AT&T just released similar news. Playing follow-the-leader, AT&T's unlimited calling plan is also $99.99 and becomes available in three days, February 22nd. Current customers can choose unlimited calling without extending their contract while new AT&T customers have the option of a month-to-month, 12 or 24 month contract. OK, who's next in this wireless game of tag? T-Mobile, you're 'it'!
