As much as i appreciate Takara doing the R&D I still agree with this.
Technically these companies are not breaking any laws. From a copyright point of view they're no different to 3rd party manufacturer's like Fanstoys. Morally its up to you whether you think it's a good or bad thing to buy KO's.
Personally, if i think it's worth my money then i'll buy it. I transformed MP11 last night and forgot how annoying it was. Paying $200 and have issues like the chest not stay in place is unacceptable. How negative would the reviews be if we got a transformer from Fanstoys that had this issue?
TT has no excuse to not fix QC issues or make improvements (within reason) for re-releases. Either that or lower the price.
