I've heard (well... read on other messageboards) lots of complaints about the Henkei Hound not been available. It's great that in this day and age a toy in this price range with limited appeal can become so scarce... Gives people something to chase.

The universe toys are both plentiful. Universe Sideswipe is shelfwarming like Sunstreaker and Prowl did. During the 'lean' stocking period after christmas Sideswipe was literally the only universe toy on any shelf in any shop... Unless they start selling it at your local milk bar there is no way for Hasbro to make this easier for you to obtain.
Cyclonus is current and at most shops... might be starting to drop off now with the new wave coming in.
