Just as I predicted: everyone who didn't get into London. A few have been's and some from the short course Dubai 2012 Marathon.
Mosop: hasn't raced since he lost in Rotterdam last year to a noname
Gebre: hasn't race in 2012
Geneti: Dubai short course, need a say more?
Matebo: ok, serious contender. Anyway, virtually unknown
Dawit: another Dubai short course
Womens side not much better, discount Mergia (Dubai short course) and you got a mid 2:21, 6min slower than WR and 3min slower than the worlds best (who will be running in London).
Geb Geb ran the Olympic 10,000m.
