Haven't seen much new information about this particular film, but there is a movie poster & trailer up for "The Avengers XXX", coming out on May 1st. Chyna's She-Hulk is in it, and it looks like it will serve as the tie-in for all of Vivid's individual Marvel parodies - "She-Hulk XXX", "Iron Man XXX", "Thor XXX", etc. Also, the promo picture of Chyna wearing She-Hulk's latest outfit looks like it is from the "Avengers" set, and not that of "She-Hulk", because it appears in both the trailer & poster. Of course, it could be from both.

There is also a behind-the-scenes video of "Avengers XXX" that has the director, Axel Braun, mentioning a little about "She-Hulk XXX".
