>>10741557It's not too late. In fact this is a pretty good time to get into it as far as figures go because they're pretty much the best they've ever been. Only downsides compared to the 2007+ golden age is the price, lack of vehicles, and less selection of characters.
As for the main characters, Hasbro has said they've been aware of the "Make the Mains" campaign surrounding TVC 2.0 and they are working on getting new/updated versions of them into the line. They recently pipelined ANH Leia, ANH Vader, R2-D2, and the Stormtrooper. Leia is supposed to be all new, the others are unknown. Vader is most likely going to be a retooled version of the Dark Times from Kenobi (which you could get now and be pretty damn satisfied with it as it is the best Vader we've gotten in the scale so far). The Stormtrooper might just be a repack of the last one they did that was Walmart exclusive and it is also pretty damn good. If you want some now, you could get the Gaming Greats Heavy Trooper version and just remove the pauldron and buy some E-11's from Marauder Gun Runners to turn them into regular troopers since they are available for retail still. For Han, you could get the recent ROTJ version seen here
>>10735973 but it is definitely not the ideal version since it's half a new figure and half reuse from the young Han from the Solo movie. For Luke you could go with the Imperial Light Cruiser version since it makes for a decent ROTJ Luke but he might be a little more expensive on the aftermarket now. Personally I would just wait on everything besides Vader and maybe the troopers. They haven't pipelined a new Han or Luke (besides the X-Wing version) but they'll no doubt come out with them in the near future.
