So... I am not 100% sure this is the place to talk about it but it seems the most logical to me so I'll go with it.
The star wars and the DC comcion exlusive packs has been revileld. I think it's safe to assume that the marvel one will be similliar.
I see some who are happy about it - because nothing is exlusive (except the package) - but I see it diferently. The minifigs that come in the comicon exlusives are ones we would never get otherwise ( like, deadpool duck), and these exousives are oprutinities for lego designers to go crazy with their choises and for the fans to enjoy the result.
And don't you think I am privilage to get these minifigs, and that's why I am complaining, I live in israel and not once I have been to any comicon. I am just happy to see some really cool figures, and I think it's cool lego makes these rare exlusives.
So, to sum up, I am not happy that there will probably not be any exlusives minifigures, but I am still pretty payched about what's the marvel exlusives will be.
