nope. BB10 is drastically different from BBOS 7. There will probably be minor updates here and there for a while. But i will NOT be able to go to BB10.
Perhaps you should search the forum or read some of the Crackberry articles before posting because this topic has been discussed to death. BB10 needs a minimum Dual Core processor to run and all Blackberry 7 devices have a single core and will NEVER be able to upgrade to BB10.
