Also, trying to figure out if the GTX2867 will really do anything for a stock block build. So many choices!!!

The issue with the GTX2860R is that you will not reach its peak efficiency island until 17psi of boost. It is really more geared towards an engine designed for boost from the outset with low compression. On the VQ37VHR with its 11:1 compression, the GTX2860R is not a good match. Granted, it will still "work", just not as well as the GTX2867. While the GTX2863 is an "OK" candidate for a stock motor, you don't really hit the peak efficiency island on the stock engine until higher boost levels than you can realistically run on pump gas.
The GTX2867R is the best candidate for the stock engine because you can run through a large portion of the high efficiency island for more of the powerband. That means less energy needs to be harvested from the exhaust gas to produce boost. Furthermore, the boost that is produced is at a lower temperature which means less heat needs to be dissipated by the intercooler and smaller cores can be used.
The bottom line is that I would recommend the GTX2867R since it is an excellent match for this engine.

What is the release date of GTX kit? Is it the same as MHI?

The GTX2867R is definitely a good way to go, even on the stock engine as I pointed out above. If you are just looking to have boost on a budget, however, the GT2860RS is still an excellent choice.

We anticipate having this kit available to ship approximately 30 days after the MHI/Garrett kits start shipping.
