Is there a MUST HAVE Xbox 360 game coming?

[Tempest]

I've been looking in some computer stores whilst I'm in town, just seeingin there were any 360's in stock.
Seen a couple of Core packs, but no Premiums on the shelf yet.

But anyhow, to be totally honest, I really don't know if I'd actually buy one yet.

I guess, the problem is, with most of the consoles etc of the past, there's always been a MUST HAVE title.

Something everyone saw that just made your jaw drop and you just had to have it.

Is there any news on a MUST HAVE title on the horizon for the 360 at the moment?

Don't get me wrong, I'm not saying the current games are bad at all, it's just that nothing has me really excited on the current lineup.
