Schneider/Modicon Products End of Life Dates

Does anyone have documentation (or a really good memory) for the End of Commercialization (obsolete) of the following Modicon products:

- 800 Series I/O
- ProWORX NxT software

Working on upgrading a system and need some justification facts if possible.

Thanks

For the software, I have seen this:

http://www2.schneider-electric.com/resources/sites/SCHNEIDER_ELECTRIC/content/live/FAQS/256000/FA256308/en_US/Concept-Proworx.pdf

It is for Proworx32, but I recall that is actually an upgrade to NXT.

Yes, I have seen that document as well. That is referring to ProWORX 32 which is newer than NxT. We never migrated to 32 and still use NxT.

I searched the web for everything I can think of and nothing is coming up except a thread from this forum:

I am trying to find documents from Schneider/Modicon for the official obsolete dates.
