More likely? Let's get real, Amtrak doesn't want to add long distance services where it looses its shirt, it wants to cut long distance services little by little, which it has been doing ever since it has been in existence. It's up to the States to fund track improvements and subsidize trains filling these gaps, with federal funds helping somewhat, with short distance regional trains - example Heartland Flyer.
I'm sure if Kansas was willing to subsidize a KC to OKC train, Oklahoma would be willing to pitch in its share. My point is that Kansas decided not to do so just recently. Several States have studies underway about improving train services, slow, higher, and high speed trains. Once these studies are completed, let's sit back and wait to see which State is willing to proceed before getting too excited.
