i feel like you're confused? (sorry if not) you just didn't really answer what i asked.
the original GOTG wave came out for the first film, with BAF Groot in 2014. The wave aside from a few figures really peg warmed, and caused alot of inventory back-up for other legends lines. Most were pretty unhappy at alot of the sculpts. (starlord and gamora specifically looked awful compared to their movie counterparts) and the paint tones on groot were pretty cheaply done.
Target then cut a deal with hasbro to get rid of back stock still sitting in warehouses, to "re-release" in a way, this old wave.. and upped the price of them ($23), and put it along side the new GOTG Volume 2 Wave 1 set (which is $20).. which includes the BAF of titus. This wave actually comes with a starlord that actually looks like pratt, and Yondu looks fantastic as well... this set is currently popping up almost everywhere.
Coinciding with GOTG Volume 2, wave 1 is the Toys R Us exclusive "evolutions of groot" this groot comes with a potted GOTG 1 groot, and a GOTG V2 baby groot. The paint apps and head sculpt were changed on adult groot to better represent his movie look. and was a vast improvement over the build a figure.
During NYCC Toyfair 2017 last month, Hasbro Reveled wave 2 of the GOTG V2 wave 2 figures.. the BAF for this wave will be Movie Mantis. and include superior versions of Gamora and Rocket that actually look like their movie counterparts.. movie nebula and baby groot are also in the wave, as well as yet another starlord.
