I believe it is quite difficult to get opportunity to work as permanent employee for a big company and always work in development project. Because of bad economy and budget problems companies will try to run the business with exitsing projects only. On average you might spend 75% of your time maintaining the applications and 25% of your time new development and enhancements.
You should consider working as consultant(contractor) if you want to work in development projects only. This is just my opinion. I think in your situation you have to decide whether you need a secured job or you want to work with hot technology. If you get both then it would be wonderful.
