Kyle Gray, the creator of Henry Hatsworth on Nintendo DS, has hinted about a potential sequel in a interview with Nintendolife:
If I got a call from EA that gamers were clamoring for a second Hatsworth (call me EA!) then I'd once again don my bowler hat and set to work on the sequel. I think we only managed to scratch the surface of British stereotypes, and would love to broaden out - into French stereotypes, for example!
He also revealed his interest in WiiWare and iPhone games:
Since I left I've been talking with a friend about making an iPhone game and have started working on a WiiWare title with my good friends Kyle Gabler and Allan Blomquist - who you might know from the excellent WiiWare game, World of Goo.
Would you like to see something on Wii in the Henry Hatsworth mold?
