I'm not going to buy MP Soundblaster just for Ratbat... that's just daft (IMO). Makes me glad that MP Soundwave is compatible w/ the G1 cassettes -- if I ever feel the urge for my MP Soundwave to have Ratbat, Slugfest, Overkill, Beastbox or Squawktalk, I can just use my G1s!Having said that, I think this is a good idea for a repaint, even if it doesn't personally interest me.
How about releasing Ratbat with their own unique repaints of existing MP Cassette moulds? That way they could have:
+ MP Ratbat
+ MP Cobalt Sentry
+ MP Frenzy (in original G1 blues)
+ MP Enemy
+ MP Flipsides
These Cassettes probably wouldn't sell well individually, but they could lump some of them in a single combined pack and reckon it'd sell. Maybe pick Ratbat plus another four or five of them.
