This has already been done a couple of competitions back. ( in regards to : Actually, a very good solution is more than 1 theme. You decide 3 very attractive themes for the next competition. Each entrant is allowed to choose one of these 3 themes to develop the entry in the next competition. )
Yup the comps have been though many discussions, debates and ideas. Us lot are worse than politicians when it comes to an overall consensus on how to go about them

- So generally I just grab a cup of tea, have a think and whip something up. Sometimes it goes well and other not so much but it's always a bit of fun regardless.
Just let the boss make the call
I've been working on an idea for the next comp. Should be fun as the voting side won't just be voting for your favourite game alone. It's also a theme which you can get as technical ( or not ) as you want. There are also two options to pick from but both have the exact same goal.
Sounds interesting
I'll be keeping an eye out
Will definitely launch it tonight
