No... if performance is already sufficient for most tablet users (and I'd argue it is - as an iPad owner I have my complaints but "it's too slow" it's really high on the list) then you won't see this happen. It will be some other product feature, like weight, or battery life, or cost, that will be the axis that you see competition focused on. Marketing folks would love to have consumer focus on a metrics like performance that constantly keeps growing and outdating old products. Other metrics, like price and customer experience, are often just as important to buyers. To give a parallel example, I don't think most HDTV owners are going to replace their set at this point for higher resolution. If you have 720 you probably don't care all that much about 1080 unless you're an AV geek. So that market is now competing on two other axes: cost (how cheap can you get it for a given size) and they're also pushing 3D.
