I'll buy new Tyros only with 61 keys. Now I have Roland G-1000. I play every Saturday at different places, and I'm little tired of g1000's weight and dimensions.

I don't like new design of Tyros2, may be I'm too conservative. For me the old tyros is prettier than tyros2. I prefer roundity then sharp edges in other things too.

Don't know much about megavoice tehnology, but I have doubt that Yamaha will include sampler too.
All I need about sampler is, simply sample player if sometime I'll wish to expand some drum set with few kicks and snares. Nothing more.
