So you went to the meet and greet and you got the scoop that alot of 1/5th are coming and you saw the 1/5th Iceman comiquette. Congrats. I am sure it was alot of fun.
I don't see how I will be eating my words on that I have never said that some of the 1/5th don't look great; it was hard to pass on the Angel comiquette at the time, but I am really glad I did. I just personally won't buy that scale because (my opinion) it looks like crap displayed next to 1/4th. The fact that most of them are still sitting available at Sideshow and the poll that I linked earlier shows that I am not the only person who thinks that way.
Honestly, other than a modern Hulk, Jean Grey (classic Phoenix or Jim Lee), and a few other X-Men characters, it is pretty easy to pass on 1/5th characters even if I would buy the statue in 1/4th. I figure if Sideshow wants to push 1/5th and not want my business, I am sure Hot Toys does.
Maybe 1/5th was a way for Sideshow to start catering to fans just getting into statues.
Jean Grey (classic Phoenix or Jim Lee) is by far my #1 want right now and if Sideshow released either of those in 1/5th it would be a huge FU to collectors who have collected Sideshow's Marvel line since it first started. There already is the AH! Black Queen 1/5th and to make Jean Grey in 1/5th when Cyclops is 1/4th would add insult to injury. If they do that, you're right; I would probably switch ship and cut back on my Sideshow purchases even more.
If they want to do one of her 'alternate' costumes in 1/5th, go for it, but too many fans want classic Phoenix or Jim Lee in 1/4th.
