1. It needs more games. And the games there are need to be cheaper - £2.99 is too much for old Mega Drive titles. I can buy a lot of them in physical format, boxed and complete, for that kind of money.
2. Oh, and how about something other than Mega Drive games? Since a deal appears to be in place with Sega already, let's see some Master System and Game Gear titles. I doubt Nintendo will get on board given they already have their own eShop for this kind of thing, but maybe Atari can get involved? Some 2600 games would beef up the library and the credentials of the machine. Be aware of the prices though - £2.99 is a touch high for MD games. It would be batsh1t crazy for 2600 titles.
3. Don't conduct business negotiations on Twitter. It looks amateurish, especially when the party you're trying to talk to just snubs you with the world watching.
4. £60 is steep for the machine. Given that it's basically just a handheld Mega Drive and similar devices are already available at under £50 with tons of games built in, the GG should be priced to match those. At £60 the temptation to buy a PSP and mod it is clearly too much for some people. How about selling it at £39.99 and cutting the number of free games to 3? At that price the machine looks good as an impulse buy.
5. Stop trying to shut up customers who point out your mistakes or dare to ask when they'll be rectified.
