Finished Layton 1-3 and Mystery Room, should I wait for Last Specter or play Mystery Journey? So far I have finished the HD versions of Curious Village, Diabolical Box and Unwound Future. I also finished Layton Brothers: Mystery Room. Since I prefer playing the HD remasters, would it make sense to play Layton's Mystery Journey until Last Specter receives an HD remaster as well?  
Or would I spoil the prequels for myself by doing so?
