Do you really understand what you are talking about?
It seems you don't really understand how bitcoin mining works.
All the 7 blocks above are not orphaned, and the block reward (25btc+tx fee) will be spendable at 100 (or 120, if you use bitcoin-qt) confirmations as usual.
A new block is not going to come out every 10 minutes. It doesn't work like that.
Instead, difficulty adjustment happens every 2016 blocks such that the
expected time to find a block will be 10 minutes, if the network hashrate is stable.
It is possible to have 6 blocks in 10 minutes, or to have no blocks in 2 hours.
The words "block discovered" and "block mined" are essentially the same.
And, unless the block is orphaned, the block reward will be spendable afterward.
