Is There Going To Be An Expendables 4?

The advertising for the latest episode in The Expendables franchise seems to tease that this is going to be the last one.

I watched a trailer for the movie which stars a huge ensemble of actors the other night and it certainly does tease that this is the team's 'last ride'.

I even had an automated private message from the official Expendables 3 Twitter account. It read:

Welcome to the crew! The EXPENDABLES are back for one last mission on 8/15. WATCH them line up for ROLL CALL!

I replied asking:

So there isn't going to be an Expendables 4?

I'm not holding my breath for a reply.

Personally, I would love for them to make as many Expendables films as they can. I love the idea of them.
